These games are all about the wasted effort, unfortunately :(. Looking at it in the best possible way this provides a sense of excitement and risk since you can loose a lot of time if you mess up. It isn't (or doesn't have to be) just gambling, at least in Moria, the first "roguelike" and the first one I played, since you can be more careful and avoid trouble (the free
CRPG Book says that Rogue itself didn't have the same degree of complexity and it wasn't as easy to get yourself killed, so if this one matches Rogue closely enough, which it sounds like it does, it might not be too bad). Though I also suspect more people who play those games treat it like gambling than learning the system (I played Moria quite a bit but never got all that good at it, though I eventually got somewhat better at Tales of Maj'Eyal). For me, they do tend to fall in the "more addicting than fun" category that I like to avoid.
Anyone who wants to try Rogue might consider installing
NetBSD in a VM or SD card (minimal install without graphics should still be under 500MB I think with the lastest 10.0 release). The
games set includes Rogue, NetHack, Collosal Cave Adventure, and some other early games like a clone of a very early Star Trek game first released in 1971. And, of course, tetris. The package system has both Moria and
Angband, which was based on Moria and has both old style ascii mode and a minimalist graphical system (and continues to be developed and has Windows and Mac downloads as well as being in most open source package systems).
Thanks for showing up in the forums :). You can get special gold text if you let GOG know about your account. If SteamDB is correct it sounds like you are using Godot engine for your first person part?
