World Of Goo just turned 1 year old and they're selling it for any price you want for this week only. So you can get it for 0.01$ if you want, that's almost like free.

try it out

Mu Online is said to be very good...
I didn't play it because my TFT gave me an error when opening it :/
also: ToribashRuler your link doesn't work... -.-
ShiftV3: I played it but the lag is ridiculous...
I hope that will improve over time...

Laggy ?
i play all the time now and there is no lagg.
But they have had alot of updates lately so you should try it out now

err....
i played it yesterday :/
i also checked the net and they say it is BECAUSE of the new updates...
my connection is good and i had no lag in the training mission so it can't be my comp either...
but the game is still awesome
sauerbraten is also pretty fun

SaurBraten IS pretty fun, but it needs more work to actually be good.

Shiftv3: Too many Bugs, lag spikes,almost slow-mo


Slapshot or Albatross 18/pangya
Tribes 2 - free too, just find it at tribesnext site
Gunz- ijji
Grandchase - international version
RF online - if you're a mech geek
O2jam- if you're into it

GTA 2 was uber.

I would say AoE or Battle Realms.

Nethack, Transport Tycoon Deluxe(?)
