What are some worthy online versions of board games?
They should be:
- Complete working versions
- On a site that is easily accessible (so no spam, lots of pop-ups or requires handing over excessive information to sign up)
- Is a true version of the original (same rules, look and feel, game play) so no poor quality clones
- Reasonably active community so there are enough players to have a game any time of day
EDIT:
To clarify they should be online games that replicate an existing board game. Not just any online board game.
