A snowboarding alien is an unusual subject for a computer game, so Stoked Rider: Alaska Alien is distinctive for being a little odd. But is it a good game? You can find out for yourself with the just-released demo, which unfortunately doesn't allow you to play as the little green Alaskan, thus removing its quirky attraction. But if snowboarding is enough on its own, grab the 78 MB demo from 3D Gamers, Gamers Hell or Worthplaying.

If you prefer your sports earthbound, you can try the demo for PureSim Baseball 2007, which is almost certainly a baseball game. The 106 MB demo is available from the game's publisher Matrix Games.

Speaking of baseball, some professional players in the US (where else?) have just formed the Professional Baseball Video Game League. If you're thinking it involves baseball games, you'd be wrong. It's simply an online tournament where baseball players compete against each other and their fans -- in Project Gotham Racing 3. Must be the off-season.
