I enjoy playing computer games from time to time so here I thought I'd fill you in on some quality one's for you to try out:
1) Braid :Time travelling and puzzles the perfect combo.
2) Call of Duty 4,WAW,MW2, all of them! check back here for details of COD LAN gaming sessions over reading week or email me!
4) Escapa
5) Oblivion, epic RPG, (unfortunately no interactive content is currently available (and since my cd drive is broken I can't play it!))
6) VVVVVV, coming soon; time trial level times, super gravitron times and more!!!
7) Also coming soon Marble Blast Gold! you control a marble and have to navigate through the levels! The perfect game for setting fastest times!
8) And now KenKen! Check this out for my page with a database of old kenkens from kenken.com and solutions!
9) I recently came across Worms Armageddon! This was a quality game and you can often find me and others playing it in the maths computers when we're not doing work!
