So I want to buy a few Resident Evil games (No more than three) and I was wondering: Which are the best for an Albert Wesker fan? I became mildly obsessed after playing too much Marvel vs. Capcom and I'd love a veteran Resident Evil fan to give me some advice. 
 
Thanks.

A Wesker Fan? This is a thing now?  
 
But yeah Humming is probably spot on. 

Whatever you do be sure to buy Resident Evil 4. It doesn't have a whole lot of Wesker but...just buy Resident Evil 4.

Code Veronica for the win. Definitely the best Wesker showing, in my opinion. I was kind of bummed when I saw what they turned his character into for the fifth game.  
Also, you might want to hang on until the fall - they are releasing HD versions of both Code Veronica and Resident Evil 4.  
Two birds, one stone.

Resident Evil 1 PS1, Resident Evil 1 Gamecube remake, Code Veronica and 5

I would say Resident Evil 5 because he plays a pretty prominent role in it, and its also the newest resident evil. You can also use him as a playable character in the mercenaries which I think you would enjoy. Then go get RE4 =p (1-3 are still good if your ok with ps1 games)

The only good thing about Resident Evil 5 is Wesker, and he's so good, it's almost worth the purchase. 
 

Thanks for the advice everyone. :) 
I ended up ordering Umbrella Chronicles, Resident Evil 4, and Resident Evil 5.  
I couldn't get Code Veronica because it was REALLY expensive for what it was.

Wesker!? Ha ha ha. I hate that guy. His voice is the worst.
