I just played my first game of BSG (solo using the official fully cooperative rules). I've got the german edition so my card names might be a bit off...
The green skill cards 1 and 2 say something like:
Action: Choose 1 player. This player may move his character and do 1 action OR may keep his character where it is and do 2 actions
Now if it is my turn. Can I move to a location in my move phase, play that card in my action phase, choose myself and do the location's action 2 times? It seems a bit overpowered but I've not seen anything in the rules that forbid this use...
