Hey what are some good PC games?  I like games like Command and conquer and sims.  Basically i need a game that i can play whenever i have time between classes and meetings.  Not online.  RPGs preferred. 

Thanks

If you like RTS then the obvious one would be Starcraft 2. The Total War games are also worth a look.

You mention RPGs so a few good ones would be Fallout 3 (& New Vegas), Oblivion (mods really make this and Fallout 3 last forever) , The Witcher, Neverwinter Nights 2, Dragon Age Origins, Mount & Blade and Mass Effect 1 & 2.

There are plenty of older games that are worth looking at too like Baldurs Gate 1 & 2, Planescape Torment, Age of Empires I-III, Starcraft, Total Anihilation.

kings bounty is cheap and fun

with armoured princess too but i haven't played that yet

Dragon Age: Origins
If you haven't already play it now!!!!!!

PC specs? they would help us to recommend games you can actually play. But games like Mount & Blade, torchlight, Shatter  and warcraft 3 should run on most computers (even laptops excluding netbooks) from the last 5 years or so.

oh and also http://www.spiderwebsoftware.com/ plenty of good old school CRPGs that will run on low end or old computers.

oh and http://www.gog.com/en/promo/jowood_collection is having a sale so you might want to look into Gothic 2 or Spellforce (RTS - RPG hybrid)

also plants vs zombies is fun

Well, Starsiege Tribes. It is free but you said not online...

It would be better if we knew the specs of your computer....

Get metro 2033, or STALKER

so what did you decide to get?
