Right Now I KNOW I have 309 games Exactly and I'm Really into platformer games ...
That is a lot of games... Platformers are the seeds to some of my favorite games like Duke Nukem 3D and Wolfenstein 3D.

(I play mostly DOS FPS's)
I Collect consoles, the Old Gaming PCs like the TI 99...
Cool! I still have my TRS80 MC10 and Color Computer, Vic 20's, Commodore 16 and 64's... but they are not set up at this time due to space constraints.

They are boxed and ready to go though.

I also Collect the Many Accessories that do with consoles like Sega CD & 32x...
Me too! Even though there weren't many games for Sega CD and 32, I try to have examples of all of them.

As for Plug n' Play I have 3 right now... one is a Mortal Kombat the other is Space invaders and the last one is Mrs. Pac-man.
I started buying them for the classics and ended up getting a LOT of these... some of the games on them are excellent for those who enjoyed arcade games. (Pirates of the Caribbean came to mind.)
Thanks for the poster image...

I only collect posters of a few of my favorite games, but most of them came with the games I bought. (Duke Nukem 3D, Heretic, HeXen, etc)
See you around...
