If you want to play lots of classic games, you may also want to consider something like a RaspberyPi or an android emulator box.

I can't say much about how a lot of emulators run on these, but many can run up to the PS2 fairly competently as well as some more complicated to emulate consoles like the Saturn (multiplatform games are usually better on PS1 this generation and while it has a lot of really cool exclusives, it's hard to justify paying 400-1000$ for some of the better titles)
