Minecr..... Hmm...
Mordor: The Depths of Dejenol.
Never heard of it? Can't blame you. On the one hand its a huge game. On the other hand its extremely indie to the point that basically no one knows about it.
It's about 2 parts text RPG, to 1 part GUI. Looks exactly like it was put together in Visual Basic, and I think it probably was.
Even still. Great game. I spent hundreds of hours on that game when I was younger. Kind of embarassing now, but it was great in the day.
Don't really want to play it again though. I might realise its not very good and ruin memories.
