It depends on the game. For RPGs I give it at least 5 hours to decide whether it's worth playing or not. I usually end up finishing most of my RPGs even though I'm not loving it. I'm currently playing Infinite Undiscovery and I don't really like it, but I'm still gonna finish it... waste of time, I know. but, oh well.
with other games I usually give it an hour or two. Or in Street Fighter 2 HD Remix's case, 5 minutes, lol.
