This must be about a 100th NV thread since 1994
The best thing proposed so far (except flashlights and other stuff that'd require making AI smarter to be able to take advantage of the light), was proposed, I don't remember by whom, but boils down to:
- Every XCom agent is issued with NVG that boost NV to 20 in night conditions
- You can turn them off an on any time
- When turned on, your accuracy and reactions suffer a harsh penalty, and brightly light tiles start blocking your LOS
But having said that, I like the vanilla "thou shall fear the night" idea, as it is both simple and powerful... although aliens? If they were undead, or demons, it would make more sense...
