I voted for Ms. Pac-Man myself, just hadn't commented on the thread.  😉

I voted for Pac-Man Junior. It was a hard decision. I have been playing Pac-Land on the Lynx and I think I like it better than the TG-16 version. Pac-Mania is awesome on the Nes and Genesis/Mega Drive. Super Pac-Man is also a favorite of mine along with Ms. Pac-Man. I have had the Coleco tabletop Pac-Man since it came out so it was played over the 2600 version. Later played the 5200 and Nes versions of Pac-Man. Both very good versions. But it is firsts for me. 

All this leads to first impressions and that was on the 2600 with the Jr. Pac-Man (I have played the arcade on Mame), but I think they did such a good job with the 2600 version that it is my favorite.

I have the Xbox live arcade compilation disc with Pac-Man Championship Edition. Just my opinion, but I feel it is a pretty good update.

It's an incredibly spread out poll, no clear winner here!
