Yes. "Fly to a tile" is not the same thing as "discard a Helicopter Lift card". Furthermore, the Pilot's ability specifically limits the flight to another island tile.
The win condition:
Get to Fools’ Landing! Once you have collected all four treasures, everyone must move their pawns to the Fools’ Landing tile. Then, one player must discard a Helicopter ...
I own both, and will attempt to tackle each of your questions in turn:
What are the key differences?
Forbidden Desert removes the 'shrinking map' clock, and adds two new clocks: each player has a canteen with a finite amount of water, and there are limited ways to refill peoples' canteens. Each "Sun Beats Down" card causes everyone (there are exceptions)...
According to the rulebook:
The Navigator may move other players up to 2 adjacent tiles per action
As it states it's per action so yes you could repeat that same action 3 times. It's a very useful ability.
In Forbidden Island, the players have no secrets from each other. There is also no real-time component to the game or other physical limitation that benefit from multiple real players. As such, you can simply play alone by playing with more than one character. Each character has its own hand and plays in turn as if they were played by different people.
From the manual:
Any character can shore up a tile that is either adjacent or underneath them. The engineer is listed as an exception because he can shore up 2 tiles per action. It doesn't indicate any other requirements or exceptions for the Engineer. It does distinctly say they must be for one action so you can't spread it around.
Some think that you ...
The question is understandable.
The Engineer's ability reads "shore up two tiles for one action", and the shore action is defined as follows: "To shore a tile, simply flip it so its un-flooded side is facing up". As written, the rules place no limit on which tiles the Engineer can shore up.
But then one considers that other players are restricted to ...
The Water Level changes when you draw a Waters Rise! Card from the treasure deck. Drawing from the flood deck never changes the Water Level. As the rules say:
If you draw a Waters Rise! card, you do not get a replacement card.
So when you draw your treasure cards, if one of them is a Waters Rise! card, then you get only one more card.
The rules list four actions that a player can take on their turn:
Give a Treasure Card
Capture a Treasure
Note that Move is an action and Shore Up is a different action.
The Navigator's card text says the following:
Move another player up to 2 adjacent tiles for 1 action.
Since shoring up (or giving a treasure card, or ...
You got it right the first time. In your example, it takes the diver 1 move action to go from T1 to T2. The Diver is incredibly useful for quickly getting around the island while it's flooded. It's not as overpowered as it would initially seem... until tiles start sinking, the Diver hasn't any other special abilities. In later stages of the game, you can ...
The rulebook only ever mentions being able to give a Treasure card as your action, so no you cannot use an action to take them from another player, you must wait until their turn to receive the card.
Also note that under the Give a Treasure Card action description on page 5, you cannot give special action cards (Helicopter Lift and Sandbags) to another ...
This thread on BoardGameGeek asks the same question. According to this post, the game developer provided this ruling:
The user of the card does not need to be on the same tile as the pawns being moved.
Yes, he can turn.
Page 4 of the rules state
The Diver may move through one or more adjacent missing and/or flooded tiles for 1 action.
There is a thread on BGG here where the designer confirms that turns are allowed.
When you capture a treasure, discard cards to the Treasure discard pile and move the
figurine in front of you.
This is also where encountered Waters Rise! cards are placed.
Discard the Waters Rise! card to the Treasure discard pile.
In addition to being able to move normally, the Diver may move through one or more adjacent missing and/or flooded tiles for 1 action. A missing tile is one that has sunk. This has been confirmed by the game's creator.
I would probably, between the two, suggest Forbidden Desert, as one thing it brings that Island lacks is specific balancing based on the number of players in the game. Desert's analog to the "Flood Meter" from Island has different tracks based on the number of players. Also, unlike Island, Desert supports up to five players as designed.
In Forbidden Island the treasure deck has the following breakdown:
5 each of the 4 treasures
3 Waters Rise!
3 Helicopter Lifts
Depending on the difficulty the Water Meter will begin between the 1st and 4th tick, giving you between 8 and 6 remaining ticks respectively.
This means in a game that you can cycle through the treasure deck between 2 ...
Forbidden Desert does play well with two players, and is a bit less intimidating than Pandemic. Just be warned that it is hard, even starting at the lowest difficulty level. In comparison Forbidden Island is pretty much a cake walk as long as you know what you're doing.
I tried: you can, but each difficulty level is to be considered one lower.
In order to be able to have a chance to win with your friend if they have never played the game and that you want to start easy, you have to put the water cursor below the first line, adding a new level of difficulty: "extra-novice".
But if you intend to have more than 4 players ...
I suspect you're asking if the board "wraps around", can the diver swim from the left side to the right side? From the top to the bottom? Answer is definitely "no" on that one, it would be mentioned in the rules if it was.
As to the other possible question you might be asking, "can the diver swim through ocean to get to another island tile", there's no need. ...
Forbidden Island can be a bit tough with 2 players, mainly because of the hand limit restrictions. I've had mostly close calls at normal difficulty level.
So if you're playing with 2 players, I advise to just play 2 characters each.
