so I completed game as cai, very good experience, but there are some things I would talk about, when I was playing I was very scared that I could by acident block rest of tree by aligning with ceaser legion, I still don't know if this do it, but I would be grateful if not or to at least know this, second thing is that first focuses for dealing with legion make us sign non agression with them, but your provinces are not doing that, and legion is not directly declaring war against us but on your mojave province which bypass non agression path, I also remember that one of provinces (I remember that it was in center of ncr) is not spawning as our puppet and we need to use command console to repair that, there are is issuse that events about defeating other nations is getting too long and some people thinks that this is end, there is also problem with research because we only have 3 slots and we possible can have an extra one but only in exclusive branch at the endgame which don't make sense ( I would put one after we deal with scentist), I also don't understand a weapon specialisation for cai because at begining I think that best is balistic weapon but I noticed that imostly get bonus for researching energy one only to have choice later to either choose balistic or energetic development which is to confusing, tere is problem with legion invasion because we only get that part after completing last focus of preparing for legion branch and don'y get if legion attack us before which don't make sense and finally factions opinion, first they are oversimplifed, because people and elites are either like us or not and all focuses change that by one point and there is also no other way to change it because we only do that by focuses, so I think that decision for dealing with this and more complex system with some decision and focuses having greater or lower valuse for opinion would be good, and second thing is that they are very important because we depend on them if we want to have good ending for cai and we are using them deal with consolidation of legion and dealing with their suprise attack, i think that we should have info about that to save some focuses for later or make decisions for that, and that's all I hope that I helped, also very good job I see that you put lot of effort in that :)
