So.. In the end.. I'm looking for a list (most likely it's a short
one) of games I could buy to this system. So I need recommendations
of games that work, are available etc...

Of course good freeware/SW games are interesting too. I know Zangband
works (has caused me numerous lost days during years) well on
Pegasos, but I'm (also) askign this for supporting remaining game
makers. .

Edit: and as it's intented to be supportive, preference to those
games/makers who do offer support and are likely to go on.
