Well, for games, prefer a plain bold BMP images. Why? The trick in games is
to do a mix between space (memory/disk), speed, and simplicity. For Images
BMP is very simple, very quicky but use a lot of space. For the majority of
games BMP images are good and perhaps the best choice you can do. But If
your game is graphics intensive in the sense of quantity (Gigs of images)
then the best deal could be on the space... All depend of the kind of game
you plan to write.
