Except in World of Warcraft, where you can spend all your time grinding out solo achievements. I don't know how good the achievements are in this game but it doesn't look as extensive. It looks like the only thing to do is raid and battleground. I'm only level 25 though, I don't play anymore because Tatooine lags way too much and I barely have the requirements to run the game, I just read these complaints for entertainment while eating(Didn't subscribe until like 2 weeks late so I can still post if I want).

Core 2 duo T7250 2Ghz 2GB ddr 667 Geforce 8400M GS 128MB 25-40 fps when out of civilisation probably thanks to the hallway and small room layout of most of the planets but it will drop down a lot when going to busy areas but is still fine to get through. In some places like towns if I stand still it will go fine 25fps but as soon as I move or turn the camera it will go down to 0.2fps. Still I managed to get to level 25 or 26 or something. The issues don't really start until swapping areas a few times or switching characters, memory leaks are horrible on 2GB ram and loading times start to take a long time. Also I have to play on 800x600 lowest settings. Can play Rift at 1280x800 low render with medium textures and draw distance just fine at about 25fps with no framerate issues even in the city.
