Coming off WOW Addiction, Please help with a game.

I just quit WOW after a 2 year addiction. I enjoyed the game, but got tired of a few aspects of it, and the life commitment needed to achieve end game elite status LOL. Now I dont know what to play. I am not set on any genre, I am just ready for a fun game that I can complete solo. I would like it to have some multiplayer too. Maybe something, an RPG that has a good solo campaign so I can build up my character to max without scheduling my life with 25 other people, and then go online and pvp. 

I like RTS too. I havent played a good one in a while, but I find when I play them I always wish I could build a huge city and then fight to protect it. Most RTS I have played you build units real fast before u get zerged. 

Anyway, I am not picky ATM, I just can't afford to buy a game that I won't like. So please suggest anything. I like FPS, but I seem to lose interest fast. 

Thank u for your coming suggestions.

Medieval total war 2 is a very  good rts, lots of building but very good.

Go back on WoW . thats all you need

Try EVE Online or LOTRO. EVE Online has 14 day trial and LOTRO 7 day buddy keys.RK-Mara

I really dont think replacing one MMO with another is what the TC had in mind.

As for RPGs, there is always KOTOR, KOTOR 2, Neverwinter Nights 2, and the classics like Fallout 2.  Diablo 2 might work as well, although I dont know how large the community is now.

For RTSs, I recommend Command and Conquer 3, Supreme Commander, Warcraft 3, and C&C: The First Decade (great value imo).

Also, when I go off WoW occasionally, I totally get back into Counterstrike: Source.  So long as you dont join a clan you should be find in terms of playtime.  Sure, I can play the game for like three hours straight if I got nothing better to do, but I can also get in a quick 20 mins before I go to class or when I need a quick break from a long project.

Best substitute, atleast for me, is definately some sort of online shooter (BF 2/2142, Counterstrike, Team Fortress Classic, etc).

Thank u all for the responses. I am downloading a demo for Company of Heroes right now. That seems pretty cool. I am really looking forward to Hellgate London, and I like the sound of the Elite package.

I have tried guild wars in the past, but it didnt feal right. 

Thanks again for all the help, any other suggestions will be greatly appreciated.
