This is a very bold and radical move and I respect that, especially coming from you who has done soooooo much for the hobby and for this forum.
As Etienne said, I'm sure this is not a "Good bye Arcade Scene" post, you will still be there, like an arcade guardian!
For instance if I start a thread tomorrow that would go like "Looking for a Space Invaders Neon", i'm sure the "Neon Police" will react

I hope we'll have some opportunities to hang around together at some party wether there are "heavy black pieces of furniture filled with electronics" involved or not!!!!
If I were you, I would have kept at least one cab to "leave the door open", but that's just me.
I always pictured you with a nice Donkey Kong cab, maybe you should get one now that you have room (just planting the seed in your mind)

Speaking for me, so far I kinda regret every cab I already sold and they aren't that many

(Galaga, Omega Race, Mario Bros Widebody, etc...)
I'm not posting so much on the forum, but that's because I lack of time dramatically, but my arcade heart still beats strongly in my chest, guys and I read your posts too
