My bro and I used to play DoD:S and other games at the same time on our damn near useless 384kbps/128kbps cable from Charter. It would run absolutely perfect, with both of our pings 30-50 when we found servers within 500 miles or so. OTOH, now we have 5mbps/512kbps cable from Charter, yet when roommates are using bittorrent, it makes it almost pointless to play online games.
I would check for HL2 Ep1... some places have been selling it for under $10 for a while now.
There haven't been a whole lot of good single player FPS games recently. Most of the good ones are a bit older.
Far Cry?
Prey and FEAR might be good choices, but I would personally only get them if they were very cheap. Quake 4 was well.
UT2004 if you don't mind playing with bots. That should be very cheap, and has excellent multiplayer as well, if your connection ever allows it.
