Currently a load of old FPS games; TimeSplitters Future Perfect, Zaero for Quake 2, and Return to Castle Wolfenstein.
TimeSplitters FP is pretty fun, a shame that the single player campaign is so short.
Also some of the scenery is rather bland sometimes, couldn't things like the head office look more 'lived in'?
Zaero is an un official expansion pack, surprisingly some of the level design and item placement decisions are better than that of the official expansion packs.
I am surprised to see that the developers even managed to put some ingame cutscenes in Quake 2.
RTCW, what is to say?
Its a fun game.
