Recommend any Legal Online

Im looking for LEGAL online games to run on our ISP which is Free (does not require royalties)

if you have any recommendation i would greatly appreciate it. By ISP i meant Internet Service provider with 155mb connection. And alot of very expensive dedicated servers to run the games that would fit my requirement.

Im looking for 5 games to run in our rack servers.

If you know any please tell me and ill set it up ASAP.

you can run fps servers

quake, ut, cs, css, dod etcetc theres loads

I think thats about all that you will find that is leagal ><
But there are soem games that you wont have eny problem but not sure if its 100% leagal like t4c. But when server filles are made by urself the company cant realy say much ><

ill have a look at it. so WOW is off the list?
