Well as I said games that are time-based and doesn't use a lot of movements, many static sprites, etc. Games that you need to make sure the time is exact for everyone.. that depend's on the game type.. in my case for example I think that would be welcome.
Another thing, how to solve the problem to make the game keep always running? Because when the windows lose focus the game stop. Would be good if there was an option to allow the game always run..
