Making 3 Suggestions/Requests
First is Holophonic sounds/audio. This would just provide more realistic gameplay. An example would be:
Your in a DM and someones shooting rockets at you. A rocket flys by the left side of you. So you would here the rocket only on the left speaker or headphone. Same thing if someone opens a door to the right of you, you would hear the door in your right speaker and/or headphone.
Not really needed but would be pretty cool.
Second is a lighting suggestion. Say you want to have a whole bar of lights like on a bus or train:
Instead of making bricks that each have a light to it, maybe a new brick could be made, that would be able to transfer light from one brick, this way you wouldnt have to wrench each brick. Heres a small diagram:
With all this light on the bus, it might be kinda bright which leads me to my next suggestion.
Third is a light dimmer or control panel type thing. Lights can be a pain in small builds, they tend to overlight everything, and it comes out looking kinda stuffty. In contrast, with large builds, there usually isnt enough light, so you have to add multiple lights. So for a large build, you could have the choice to set up one really bright light, or you could use my previous suggestion. For small builds, it'd be nice to be able to dim the lights so they arent so bright.
Anyway those are my suggestions for now, comments?
