Rogue is a great game, and you can play it for free in your web browser on the Internet Archive , or download it and play it in dosbox. Don't give your money to some random holding corporation that acquired the IP of a developer that went bankrupt, none of your money is going to the people who made the game....

I mean it really isn't

the entire point of a roguelike is that each failed run unlocks things that help you win your future runs, without that it's just a pointless waste of time if you die

You do not own the rights to Rogue, you have absolutely no right to sell it. I contacted Steam about it and suggest other users to do the same. Wanna make a few bucks? Then make your own game instead of trying to cash in on other people's work.

Rogue is a cute little game, but I'd recommend playing Nethack instead. It's like Rogue (roguelike!) but more polished, more complex, overall just a better game and it's free.
