Well Rare Replay includes a few games in it that imo are fucking classics like Conker (but the best version is Live and Reloaded), Ghoulies, Battletoads, Banjo, Viva Pinata, but most of those are available on pc by other methods afaik, just not bundled with "Rare Replay" (which means Conker is better emulated on the xbox OG, because bot battles Squirrel v Bear.)
