As proto-DOS as it gets: No sound, no graphics: Just ASCII characters in color. And you know what? I just meant to play a round or two and see what the fuss was all about and now I’ve been binging for two weeks on it and still can’t get enough. This first grade hack-n-slash crack and thus I would like to suggest it as Game of the Month so I don’t feel such alone in my addiction 😉
Rogue is great, personally I think Nethack is a more interesting game though, took the idea of rogue and just ran with it! It’s really stuck the test of time better too, and though it’s been out since 87 the latest release was only 9 months ago!
I mean, either of those would be good choices. I’ve played a lot of Nethack v3.4.3, though the nethackw.exe version for the most part. But I’m sure you could ask some experts to come on; you could ask the Roguelike Radio people to mention the podcast for either one, to get more people playing along.
