yeah, a lot goodies missin' there
TBH, my "list" was mostly based on Pauls opinions on pcengine.co.uk, and what I know for myself. And what I know is based mostly around the few reviews I read back in the day, or the quite well known titles.
I know there are a few games that divide opinion, but usually they're quite cheap. I'm thinking of getting a "job lot" of games to fill in my collection cheaply.
