Oh I remember those days. Tom Clancy games are still going. Still plenty of Internet cafes here which offer them.

If I recall correctly I had a FPS period then with UT, after finishing Gothic II. But that ended when Spellforce II was released and I think AoE III followed shortly after that. Online RTS was my drug before raid games.

FPS was mostly the different Agent 47 titles. I even got them for iOS and was in Top 1% (non-IAP) but stopped playing because it required a FB account to rank.
