I think I might have posted about this several years ago.
Diablo 1 is a pretty old game that redefined the RPG genre for decades to come. Released in late 1996, most of its systems and features still hold up today. But it does feel dated.
By default, nowadays, the game's resolution is pretty low and it's in 4:3, so it's stretched out when you play on a widescreen monitor. And it's pixelated. A lot. Add to that the fact that it's a 1996 game, and you'll notice weird user interfaces, like the way you trade with NPCs by scrolling down lists of items without much detail. So weird and outdated. Not user-friendly at all. That's just a small example, here.
Now, a guy known as Mordor created an extensive, giant mod, that brings Diablo 1 back to today's standards. Again, it's a GIANT mod in active development as we speak. Pretty crazy when you think about it.
It's amazing. Once you've tried it, you can't go back to old vanilla Diablo 1. I promise.
Let's check it out. You'll find links to download the mod and everything you need to know at the end of this post.
