Good games for low end pc?

I'm looking for some good games for my laptop, its a windows 8 laptop and its not too good but its decent. I already have gta sa, gta 3, terraria, 7 days to die, and minecraft. Please don't recommend games like old arcade or anything, cause i already have emulators. I prefer open world games over anything, but if there's other games youd recommend, do so. Also, i've already played world of warcraft and it runs erfect, i just can't afford membership.

I would try starbound. If you like terraria and minecraft you may enjoy this one. Its still in beta so its not quite finished yet, but its still a lot of fun. Its 15$ right now so its still cheaper than most games tend to run.

Raven has a good list (you shouldn't have much trouble playing vanilla Oblivion on high-ish, but Skyrim would have to be low), but if you're looking for more open world RPGs, I highly recommend Divinity 2, Witcher 1, and both Two Worlds/Risen can be pretty fun.

And you could probably play Rome, Medieval 2 or Empire Total War, great games that you can only play on a computer. Next time post the specs too!
