1. Why i cant run in the dungeon?
2. Why i can run in the dungeon, but only i go down left or up right?

This is very annoying. Sorry for my bad english, i am german.

I'll try my best to answer your questions:
There was no running in the original Diablo, GOG version doesn't change the original design and mechanics of the game. The same goes for 8 directions in which the characters can move. I think there are some mods that add running to the game, but it might be only in town. I don't think there are mods that change number of directions the character can turn. That's just how the game was designed and it might be due to the game being turn based at first during the development. Those changes have been applied in the sequel though, you might've played it before trying the original Diablo.

Yes pretty much what the last reply said. There are a few mods that sort of add "Running", but they also change waaay too much of the original design of the game in my opinion.

It has been a very long time since I played Diablo so I forgot some things.
Are there any "stashes" to use to store items like spellbooks for which I do not have the refquired level of magic, and other usefil items?
I doubt it, becuse it was a big deal to have some in the sucessor games in the series.
But maybe I am wrong, so if anyone knows for sure, yes, or no, please drop a reply.
Thanks, Muzzien

ok thanks

I have sound at start up but nil sound with chararacters talking or fighting

I have some questions for Diablo.

1. Why are you so evil?
2. Are you coming back to Sanctuary for the fourth game?
3. What do you think about the cow level?
4 What you think about your friends at the top? Who'd you think besides yourself's the pick of the crop?
