I think it’s the NES for me too. It was my dad’s, and he kept it in good condition. He mostly only had sports games for it though, and Super Mario Bros. I’ve heard the NES came with a combo cart for SMB and Duck Hunt, but we don’t have Duck Hunt and Mario is on its own cartridge. We also don’t have a R.O.B. I have no idea what that says about what time period or in what package combo he might have bought the NES.
Most recently, I got a copy of Super Mario Bros 3 and I’ve been playing through that. I also still like buying new games for it whenever someone like Limited Run publishes them. When I was there last, I bought Alwas Awakening and it sure feels wild to be playing a game on the NES that’s also sold on Steam.
