Could you add an option in settings to play without action points kinda like how you allow people to either play real time or partially turn based, I understand that you want the game to play similar to how it was before but allowing a toggle for this feature would be amazing for those of us who want a combat that feels a bit more like the other 3D games.
I also think it would be nice to have a description for the majority of items that says what they are and what they do, I can't count the number of things I have picked up and had no clue what they were
Lastly I believe this is an amazing project, I love the idea of making Fallout 2 in a whole new engine separate from any other fallout game, but I think it would be good for you to allow volunteers to help out, this doesn't really have to be programming a new location in or anything but I think people could definitely help with things like working on the map a little and also a big help to giving NPCs dialogue options
