Grimrock

To pass the time until the release of Grimrock 2, I'm currently playing the MASTER QUEST, since everyone on Steam rated it so highly (my first Custom Dungeon installation). So far it's awesome, I'm only on Level 2 so far, but there were already a couple of surprises! I really, really hope, the creator of the original Master Quest will do something similar for the G2 as well, expanding on Areas, pimping Puzzles and Fights, so a second playthrough won't be so predictable.
I don't think, that the Quickbar adds too much to the game, though. Just blocks my view from oogling at the prettiest walls ever created for an RPG.

After Master Quest, try the One Room Round Robin mods.
(There are two.)

** The Quickbar is ~foremost... optional. Press the comma key to toggle it on or off. As to its uses... Its main function is weapon swapping and one-click potion use.

I have not decided whether I might try to make Legend of Grimrock 2 - Master Quest. I haven't even finished playing the main game yet, let alone opened the editor yet (RL been very busy past couple weeks). It would be an even huger undertaking than the first one. We'll see.

Komag if you do decide to do it man you have one big task ahead of you, and If you wish to do it then good luck
Also you have my support behind you, if that means anything

EDIT: Oh it wont be like the last LOG you will have to do all the elevations and that stuff, so again I wish you luck on this
