No guesses yet?
If it is too hard I could post more screenshots.

Master of Magic

We have a winner!
I thought Master of magic was a great game.
Now for the spiritual successor, you can read all about it here
Your turn.

You couldn't find bigger screenshots? These are 160x100. I doubt the original had THAT low resolution :-/
Yeah yeah, I'm just bitching 'cos I have absolutely no idea what it is. Never saw it before, afair.

Space quest 3.

correct!

This one should be fairly easy, great game though.

eternal Darkness
I only play the demo
I will play the full game one day...

Not eternal darkness

I think it's Severance/Blade of Darkness.

Yeah it is, Ralackk is being tricky by not showing off the signature vast dismemberment and bucket of 'blood that actually flows' level of gore.
Now thats another game I'd buy on GOG, I never managed to get a copy of my own, I had to keep borrowing a mate's copy.

Yea it is.
It would of been way too easy a guess had a shown any of the blood or gore effects. I managed to snag a copy of it for £1 from ebay with clive barkers undying for another £1, after only playing the demos for both, was extremely pleased with that deal.

well it's been more than 2 hours, I reckon we open it up to the first person to add a new game

Real easy one here :
