Let’s do it. This isn’t meant to be a pissing contest or a bragging exhibition. It’s more like a “portfolio of games I’ve played extensively”. So maybe make a section for games you’ve legitimately beaten and then maybe another section for games that you’ve played a whole lot but never quite beat or only beat on some pussy setting. And maybe a section for games that you’ve played a lot that don’t actually have endings (like Pac-Man).
I’ll probably be the only one that actually bothers to make a list but do it, anyway.
EDIT: Some further info . . . fighting games. Okay, technically, I have beaten a lot of fighting games because, really, that’s no big deal. Most of them, even the harder ones, only take a few hours or often under an hour to beat on the medium setting. So when it comes to fighting games only include the ones that you actually liked enough to play a lot and pick up often just for fun or perhaps played through with several characters.
Also, my list will probably have a section for arcade games for which the greatest skill required for completion is the ability to keep pumping in quarters. Thanks to (the emulator) MAME I have “beaten” many of these types of games, such as FINAL FIGHT and METAL SLUG but I don’t really want to include them in the same company of games for which completion is a big more meaningful like say FINAL FANTASY VI or SUPER MARIO 64.
I dunno, do what ya want fer yer list.
