Here's the trick part of the question: no backwards compatibility allowed.
You have to choose one console in the history of gaming and stick to it and the games that were specifically released on it, whether they're exclusive to that console or not. Specific ports and remakes are allowed, but like I said, no backwards compatibility (i.e. PSN).
Obviously I can't fit in *every* console in the poll, so I'll just list the most recent and for everything else please specify as "other".
EDIT:
1)Let's assume you're not constrained by your personal collection and have access to all the titles of the console of your choice.
2)Let's also assume you're free to replace your Xbox if (sorry, WHEN) it breaks... with another Xbox. Same goes for every other console.
3)This thread is about consoles, not PCs. The "other" option is for all the gaming consoles that didn't make it to the poll, not for PCs. If your gaming station of choice is a PC, that's fine, but please vote/post your next best pick regarding game consoles.
