Thank you Chris! I totally agree with you... Graphics aren't what made Xcom 1 so scary but still graphics can definitely help increase the immersion and horror of the unknown... but perhaps sounds and gamplay do play a greater role in that department like you very well said.
All I know is that the magic that games like fallout, diablo 1 and other isometric games had has somehow been lost on our transition into 3D engines.
Anyhow, I do hope you get the formula right so we can all experience the terror we are used to from 1994!
By the way a very minimalistic UI really helps with immersion so if possible make everything UI, even the blocks that appear on the ground when moving units, as minimalist and unintrusive as possible. The more UI we have the more we are reminded we are playing a game and no really exploring a crashed UFO.
Keep it up Devs!
