I use to attend TTLG and played plenty of great fan missions. I think Dark mod is really good, played a few missions. Waiting for campaign and then try other, newer missions. It is improved in terms of graphics and atmosphere, it is more stable and plays better than Thief 3. But I was little dissapointed with AI. From what I have seen in the game, AI isn´t improved from Thief games at all. What I expected, and what I also expect from Thief 4 is not super graphics, but AI on higher level. Just a few examples: -Knockouted guard is found by another, he start looking for a murderer right away, no searching him or check him if he is not asleep. -When the guards are in searching state, they still walk mindlessly towards walls, nothing like becoming just suspicious and try to look around, or become scared or try a different patrol route, or hide in shadows himself. -I didn´t notice guards waking up after knockouts, it always bothered me in Thief games. The only difference between backstab and knockout was different weapon usage, he won´t wake up anyway. -People doing real things. Like there is dinner in the manor and then they all go to sleep, or to living room, or there is some kind of event that night and you have to take advantage of that. Something that was in Thief games, but in very primitive way. Also what bothered me a bit about Dark mod were some animations. Guards should be sleepy, tired, doing the job they don´t like very much in the time they should be sleeping at home. They should walk lazy and have more realistic physical proportions. I´m not talking for TTLG community here, it is the way I see it, but maybe it´s not just me. If I listed things, that work that way in the Dark mod, that may be because I played older version. Sorry if my english was bad, it isn´t my language. I hope contributed to the discussion.
