Pac-Man Museum came up a bit back.
Its rather pricy for what literally amounts to a bunch of easily emulatable/easy to find games (And Pac-Man Battle Royale) at $20, and its got some video issues (You can't resize any of the games, and the game is locked at 720p because Namco doesn't know how to make an option for PC resolutions apparently.) but I'm having fun with it.
The package entails:
Pac-Man (Duh)
Pac-Mania
Pac & Pal
Pac-Land
Super Pac-Man
Pac-Attack (Genesis version specifically.)
Pac-Man Battle Royale (The 4-Player Arcade game that came out recently, Local Multiplayer only though.)
Pac-Man Arrangement (NOT the awesome 1996 one with the bitching music, instead its the one from the PSP Namco Museum.)
Pac-Man Championship Edition (The original version, before DX and DX+)
Ms. Pac-Man is DLC, its free till the end of march then it becomes a staggering $5.
The most fun here is getting stamps for beating set goals. Problem is a lot of them are "Earn X Points" and the point values rack up to the 500,000 marker, which on the arcade games is [tornado fang]ing difficult as hell (so far the easiest game is PSP Arrangement and I still only managed 300,000 by the end of the game.) Collecting stamps unlocks little visual trinkets in the "Pac-Room", which just amounts to little props and the characters from that apparently terrible TV show.
I bought it because I've been waiting for this for a while, sucks that the 3DS/Wii U version got cancelled but it works fine on PC. But I can't recommend this, its only really for people who really really want to play lots of different Pac-Man games, who knows, maybe they'll add some more games later down the line, I'd love to see Pac-Man World or the Midway games.
