I believe it's Netrek.

Correct - I would have been worried, if Picard didnt know this :)

Netrek is the worlds first internet team game, or so I have read. Anyway, used to be alot of fun and its supposedly still being played.

http://www.netrek.org/ for those who are interested.

Yes, I played it myself recently.

I'll post a new screen shot once I've finished work.

Ok, here goes.

Rampart City?

I think it is Omega

Correct. A sadly overlooked rogue-like.

Your turn.

It should be easy

I have definitely played that, but no idea of the name.

Pooyan

Apple ][ version by the look of it:

Ok next one:

C64 actually, but you are, nevertheless, correct with the title!

Ah you see, I discounted the C64 version because all their shots had a blue backgrounds - I guess it must have been some kind of primitive day/night cycle!

No takers for mine? here's a clue - it was a game based on a British comic

It could be Oink! on the breadbin, inspired by Oink! the comic. Rubbishman in the screenshot, I believe.
edit, hm come to think of it, it is wrong colour for the c64, so a different version?

Yep, that's the one! I was a huge fan of the comic as a kid..
Yours of gos

Hm - lets try this one then. May be a bit easy?

Proteus?
