Tony Hawk Pro Skater 2 (PS1) - $1 via Thrift Store (OpShop)
Snowboard Kids (N64) - $5 via Salvation Army Store
Metal Slug 4 (PS2) - $ 4.50 via Cash Converters (Pawn Shop)
XIII (Xbox) - $1.80 via Cash Converters (Pawn Shop)
The PS2 ports are much better than the emulated Metal Slug Anthology (Only 6 is ported in the collection) far less slow downs and runs smoother, look great via component cables. I now own Metal Slug 4 and 5 for the PS2.
XIII for $1.80 was a no brainier, the case and slip is a little banged up but still great price.
