I'm going to buy a bunch of consoles to be able to play games on hardware.
What consoles should I get to cover the largest possible range?
The Xbox and Xbox 360 would have to be on their own as they don't offer the ability for backward compat.
The Wii can play N64 (through VC injects) and Gamecube, while the Wii U would be only for Wii U games.
The PlayStation 2 would be able to play almost the entire library of the PS2 and PSX, apart from the handful (like 20) of PSX games that won't work, which would be addressed later.
Not really familiar with SEGA systems, so how would I go about getting Genesis, Saturn and Master systems playable to the best extent? I know there's that custom-built SEGA machine by some third-party called the Terminator or similar, so that might be worth a look.
As for handhelds, the PSP would handle the PSX games unplayable on the PS2 as well as it's own library, the Vita would be it's own thing and the 3DS would be able to play the 3DS library. On top of that, the 3DS can be used to play GB, GBC, NES, SNES, GBA and DS libraries natively. The PSP also has a metric shit ton of other emulators for earlier systems.
Other than that, what consoles should I look at? I think that covers the main 3 manufacturers at the moment, plus SEGA. I'm not too fussed about original hardware for pre-5th gen as they're much easier to emulate either on a computer or another console.
I suppose if nothing else, console/hardware thread.
