Hey Salmjak,
I hope you know that your computer is very bad ^^...
Well, you were looking for some games that can be played on a computer like that(By the way, every computer got a graphic-card).
The games that could work on your computer:
Monster&Me
Eudemons
Maplestory(you will lag at channel 1, thats sure and it probably wont work but give it a try).
Metin2 (Recommened)
Crounous
Supreme Destiny
Conquer Online
Knight Online (this game gets an 'A' from me if we are talking about graphics and gameplay but the bad part of this game is: Most ppl talk turkish, you wont be able to log in all the time without a premium-card, you will get ksed 24/7 and almost no1 will help you in the game)
Well, if you need more games just mail me ^^
(my mail is:
mohammedali_afzal@hotmail.com)
Have fun!
(by the way, i got chars in some of those games, so if u ever need me just send me a mail)
