I vote no. Here's why:
I have a pristine Atari 400 with just about everything. I could sell it and make enough to buy, what, a few joysticks.
I could even add Atari functionality to my soon-to-be-started cabinet. But there's something magical about popping in that Star Raiders cartidge and playing the first-ever fps.
Instead, the 400 is going to sit on it's own little cabinet -- wires and power supplies stealthed -- next to my Mame cab. I'll run a coax to the mame monitor, and be able to play "Shamus" now and again.
I say keep your console games -- perhaps someday you'll wax nostalgic over them. You'll never be able to replace them all, and chances are that you took far better care of your stuff than others have.
I played a game of Star Raiders the other day -- probably the best use of 16K ever programmed. If I still had my Sega Genesis, I'd put that next to the Atari 400 and play Sonic once a year.
Having posted that, I think I'll get me a "Pong" game. Hopefully the one with the lightgun. That rocked. I look at my game room as a "history of home computing."
I'll bet those console games will look nice in a display case next to your cab. You can always make more money.
