1 When mutants die from flamer they look exactly same as humans who die from flamer. So do mutants really shrink that much? I think giving mutants normal death animation would be a better idea.
This has been the case since Fallout1/2. It's an oversight of Interplay/Black Isle. x'il on NMA fixed it, but I doubt it's worth the hassle when we'll have 3d critters anyway. Kudos for suggesting such minor stuff - you have a good eye for smaller things too.
2 When enemy is down there is 100% to steel him uncaught, but its a bit strange when for example there are 7 vc caravan guys standing near one knocked to - hp one more caravan guard and you steal from that one and everyone is happy like nothing happened. I think faction members should look up each other.
3 When you kill faction members in encounter it modifies other (who are not in that encounter) factions reputation. But for some reason it rises only to 0. So for example if i have -100 with vault city and kill raiders, i cannot get my reputation above 0. If faction likes what you are doing when the reputation is in -, how can they dont when it comes to 0?
