i totally keep my systems, except i believe my dad still has my Atari2600 in storage, and my Sega Genesis Tower of Power i stupidly sold when the PSX came out, i don't regret the PSX just regret letting go of my Genesis ToP... i'll never sell another system again, selling the Tower of Power is that big of a regret for me...
my Playststions are all hooked up and running from the PSone to the PS4 in a nice little row under my TV... of my Nintendo systems i only have the Wii hooked up because it plays GCN games as well and the SNES is having issues, think i need a new A/V cable for it, the NES is boxed up... i still have all my handhelds across my headboard in front of their charging cables that i have coming out from behind the headboard for convenience and cable maintenance...
yeah, i can't bring myself to sell a console or game ever again...
