Steam Hearts on PC Engine has a pretty big sidebar too.
As far as Jaguar goes... I actually let mine go this year. I just never played it When I did it would be for games like Tempest 2000. In truth I would rather play the trippy Tempest 3000 on Nuon though. I even tried some of the CD games but they just didn't grab me.
That's a fine way to be, no reason to hold onto a system if you never play it. I let go of a gamecube, that I only had for the Gameboy player attachment, and I really only played the Gameboy color version of Shadowgate on it, hahaha. I did buy the Final Fantasy 1 and 2 cart, but instead I picked that up for the PS1, since I have the PS2 for game compilations. When I get the urge to spend days going through FF1 again, I have the CD around.
I let go of my odyssey, and Odyssey 2 systems. Same went for intellivision. Just never played them, and rather let them go to people who would enjoy them, or at least like them sitting around. I maybe should have held onto the Colecovision, but I don't miss it that much.
Less stuff taking up space.
