fixed the older Dawn of War games however don't need online activation. Oblivion was awesome (I played on the 360 version) and I found it a lot easier to get into than Morrowind. Titan Quest was pretty good
Not to forget worl in conflict! it keeps me awake at nights and late for work!!! Also Bioshock Farcry (and farcry 2 altough I am not sure if you need the web to activaite that one)
+1 for Elders Scrolls games, like Morrowind or Oblivion. Both will provide a good deal of gameplay hours and are great fun. Does Supreme Commander require online activation? That is a stupidly good game.
Morrowind over Oblivion definitely. If you're into FPS's check out Doom 3, great game imo. RPG's I'd say check out Fable or Morrowind.
Your surely better off on a landline than mobile broadband Talk Talk basic package for phone and broadband is Monthly cost (incl. line rental) £13.49 but it does have a 40Gb cap and it has a £30 connection charge up to 24Meg but there's no way you'll get that more like 5 id imagine Im sure you could probably find slightly better deals and you wont have to spend much more than £10 a month
