You are mentioning titles close to my heart
My collection of really old games is quite comprehensive because I just LOVED all those early ones - so I always try to keep one
of them at least on the go
And I find that if I'm stuck on a more modern game, going to my current oldie for a while re-invigorates my brain somehow.
So I HAVE to keep one on the go
Well that excuse is as good as any other, don't you think ??
