Which is a good rpg game that will work on my pc, my specs are: Intel Core duo processor 2.8ghz, 512mb ram, at?

Runescapes ok, but my guess is you have already played it, who hasn't, my only worry for you mate is the RAM, I had the same problem, I only had 512 mb, to play games on your PC it is recommended that you have atleast 1 GB, I had 512mb and got it upgraded to 2.5 GB, I totally recommend Runes of Magic, it takes a while to install and update but its worth it. Its like WoW but hasnt got a monthly fee, when I had 512 mb however runes of magic was really bad but after getting more RaM it makes gameplay more smooth. RAM is not that expensive so it wont burn a hole in your pocket like a new video card would but I totally recommend you upgrade it you will soon see a difference in your gameplay.
