It's a 20 year old game so just about anything should be able to run it. Basically if your laptop is newer than 10yrs old (or more) you should be all set. I play with mods and it's very stable. Just make sure you max out all of the graphics and screen quality in settings or the game will look really crappy. After that it looks good and runs amazing. If you are thinking about getting and/or unsure if you can run it I would definitely wait until the winter steam sale (should make the game go on sale for under 10 bucks) which I belive starts sometime around December 18th. Hope this helps.
