I'm in the middle of redefining what my collection is all about. Over the years its been built of games I wanted to play. When we started Vgcollect, I had started buying Game Boy games and accessories, and I've built up an impressive set. I had already begun my Castlevania collection before then, with loose carts and CIB disc games too.
Then I bought my Saturn and nostalgia took over, causing me to go for the US set. After buying a lot of stuff that I really had no interest in, other than looks, I decided to trim that down.
Now, I'm back to where I was originally. I'm gonna just buy games and systems I want to play, and skip what I don't. That means, I'm usually buying RPGs and SHMUPs, or franchises I love.
So I guess my focus area is Castlevania. With a bunch of games I like behind it. Of course, I can't pass up a bargain bin with cheap Game Boy games, cause I am a huge sucker for that system...
