Hello CookingMaster!
In regards to the Office Suite stuff, have you looked into Kingsoft Office? Check it out, it's just like Microsoft Office... but free! And I've yet to have any issues with Kingsoft to Microsoft, or the other way around.

Also, in my opinion, Linux is great and no matter how many times I switch back to Windows for the sake of normality, I can't stand it and have to go back. Now as you probably know there are a lot of different distributions, or versions. The most popular being Ubuntu. I use Elementary OS. It's an Ubuntu derivative.
As far as gaming goes, I use Steam. If you've ever checked out an
Humble Bundle, you'll know that there's actually a
ton of games that support Linux. I've had a lot of fun playing games I bought from the bundles. Plus, Steam has been able to get their games to run
faster on Linux than they do on Windows.
I really recommend you stick Elementary OS or Ubuntu on a flash drive and try it out. Dual boot it with windows to start if you want to try it out full time. It takes time getting used to, but after about a week you'll realize how great it is. Open Source is the best thing since sliced bread, right? Haha.
Good Luck in trying it out, if you do.

EDIT: Forgot to mention, Kingsoft office is still in Beta and may not be 100% complete. They plan to finish it soon.
