Like most things, games can also be useful to some extent, it depends what attitude one has towards them. There are many examples of games that actually develop a specific skill base, but my favorites are blackjack and roulette. The excitement is different there, it's not down to luck you have your skills, it's just nice when you know the croupier is trying all sorts of ways to take your money but you don't give in, you know his next move and you beat him.
