I like old skool RPGs which I now realise were very tactical and so like chess. Shining Force in particular (think Final Fantasy Tactics).

The second Shining Force even had a chess battle although not using any chess rules or anything.

I have a question for all you chessheads. What genre of games you like the most? Don't know why, but I think that chess and role-playing games are very similar. in both cases you are building and enhancing your character, just in chess case, you are literally in first person view...
