What can I say I love older games, I actually got my start on a Coleco Gemini. Then worked my way up with stops at the Genesis, PS1, and a couple of portables until finally my latest purchase a PSP. You might be surprised by this I actually got it for the classic gaming collections out there rather than any modern game...even though I own a few.
I really love playing some games I honestly never heard of before like The Knights of the Round on my Capcom Classic Collection reloaded it's a really fantastic game. The same can be said for ever new find for example Capcom Classic Collection reloaded has this great version of 1941. Namco Museum Battle Collection where just about ever game is fantastic. Midway Arcade Treasures Extended Play, Taito Legends Power Up are both great but the real find was SNK Arcade and Top Hunter. I wonder why I never heard of such a great game.
Meanwhile Hot Pixel and Space Invaders Extreme are modern takes on what is really old school.
I even found a few emulators that work on my non modded model. One for the NES what can I say I love the Donkey Kong games, and one for the 7800 what can I say Food Fight is fun.
You can go modern, yet be old school.
