I came across this per accident, dl-ed the Win release version 2.3 ca. 10 days ago and have been playing quite a lot since then (campaign, one difficulty below normal for the start).
First a big thanks to everyone involved making this game, I was in search of a more modern X-COM style game for ages, and UFO:AI is really a great achievement. It's very addictive, and fun to play.
Having an ATI gfx card I had initially trouble with a black geoscape and ugly stripes on textures in the battlescape, but after reading the FAQ and some forum threads I found the right settings that work. Since then the game has been remarkably stable on my machine, I had a CTD sometimes, but overall it's rare.
One thing which gives me headaches right now is the slow campaign progress and the high number of missions. As said, I played quite a lot recently, but soon I'll be more busy with other things. However, during the last days my campaign progressed ca. 1 year in game time. In that period my statistics show hundreds of battles, over 60 base attacks alone. And I didn't even play every mission, even stopped UFO interception for a while at all since I just found it a bit too much. At that pace I feel I have to devote the rest of my life to end tis game ...
Nah, I actually like long games, but of course if things take simply too long people could lose interest or might feel tired. I read this point was raised several times in other threads, so it isn't new , but I wanted to stress its importance. Still, a good thing is that even with the campaign going on for ca. 1 year I still get sometimes to play maps I hadn't seen before, which is nice and keeps motivation up.
There are some things I didn't fully understand yet. I skimmed the forums, but if they were answered already I didn't find the threads, so maybe someone could help me out here:
1. Is there any way to get rid of a base you don't want anymore? I found a thread debating if it should be possible to destroy the entrance like all other buildings. I understood it's WAD that the entrance cannot be destroyed in the same way - so is there no way to get rid of a base? I built one I don't need, and while the Aliens attack my HQ and main bases a lot they never attcked there, so it seems I'm stuck with it....
2. What does "production limit" mean? I first thought it means the number of items you can build of one type, but that doesn't seem to be the case. It's also different from the number of workers producing.
3. Is there a way to see in the UFOpaedia what hangar size you need for a certain craft. It seems some don't work with big hangars?
4. The interface feels sometimes not optimal. Is there a way to configure what keys do what in game? Or for example, I'd love to use arrow keys to rotate the planet in the geoscape - is something like this doable?
That's all for now, I'm sure I have more to ask later. Overall playing the game so far has been a great experience.
