'till death do us part

[DreamcastRIP]

As for which gaming platform I would never let go then I don't think there is one. It's only video games and they're not that important in the grand scheme of things.

It's just a bit of fun but just to let you know, there is no "grand scheme of things".
Whatever you hold as "important" is ultimately, not, when you're gone. 

Having given the thread's subject matter some more thought I've come up with an answer of sorts. The one game from the vast number of games I own that I really wouldn't want to do without is OutRun Online Arcade.

However, as I have that game on PS3/PSN saying that I wouldn't like to do without it is tantamount to saying I wouldn't want to do without PS3... and there's no way I want to list a Sony console in preference to all the others I own!

So my ideal platform would be a Blu-ray Disc player and media hub with built-in OutRun Online Arcade that doesn't have a Sony badge on it! then I'd either go for,

* Jaguar - for the sublime Tempest 2000 using my modified rotary controller, or
* Dreamcast - for the likes of Rez and both Samba de Amigo games using my official maracas contoller setup

Online OUtrun sounds great to me!

(so does Rez on Dreamcast )

I already said Lynx but having thought about it a lot I think I would now find it very hard to get rid of my Jaguar collection given the time I have put into collecting it and taking around the country to shows (my jag is now a minor celebrity  )

I think I would have the hardest time getting rid of any of my systems, i'm such a hoarder   

The one that i would most like to keep would have to be the Megadrive as that is the biggest part of all my collection and by far the part that i have spent the most time and money on.

It's unlikey that I'd ever actually sell any of these, but if I really had to....

3DO - The FZ-1 looks so cool though
Master System 1 - Prefer the look of the console, but I added RGB to my MS2 and the picture quality is better
ZX Spectrum 48k - I always use my 128k instead

Everything else is definitely staying

Atari Jaguar
Atari Lynx

Far too many years and money gone into collecting (and still am) for these two to sell them.

Pretty much the same as me there mate

This too actually.

Although I did sell my Game Gear, Spectrum and Atari 8-bit collection. I sold the GG because it was terrible and offered me nothing except GG Shinobi while I sold the A8 because I was made a very good offer on it and it took up a lot of room and didn't get used. The Spectrum collection went because loading games on it was a pain and emulation for the Speccy is perfect these days. But having said that I would really like to get another A8, probably a XEGS (the console version) and a multi-cart for it.

I did sell my CD-I. Miss it from time to time. The Turbo Graphix-16 would be the system I would part with last if I sold everything.
