1) What did you particularly like about the TL? Did any characters stand out?
I liked the in-depth coverage of global politics, how you didn't shy away from the brutal atrocities of this new 20th century. and how you made even the best of people and nations seem heavily gray with the audience being forced to question of an anti-Nazi Mussolini even with all of his crimes may have been worth it. For most other timelines historical figures are either made saints or devils with the morally neutral or gray just made to be mediocre or unimportant. Here the line was heavily blurred and I really love it.
Patton was my favorite character overall though several others stand out. Wallace's fall from grace is a real tragedy that is partially of his own accord and no matter what you may think of current politics, Wallace is definitely the worst a President can get. As said before Mussolini was well-written due to his dark grayness. Aflack was horror done well. Malenkov leading Russia to an Orthodox Agri-state was definitely interesting and very original. Overall every major player was enjoyable and I think the real question should be which characters did the readers think were badly written as I can't think of any off of the top of my head.
2) How was the writing style/flow? How did dialogue and description feel?
Overall I liked it with the exception of long text blobs that would come in every other update. I do sympathize somewhat since I used to do the same thing, but there really is no need to have every text selection be one huge long paragraph when it can just be three or four. The South Africa portion on 2020 was almost unreadable despite it being one of the best parts because of this.
3) If you could suggest an improvement point, what would it be?
I don't like how the fall of Fascism was handled as I feel like it was way too rushed for narrative convenience and to give the world a near perfect victory for democracy. Perhaps I'm too biased from OTL and the ability of the Soviets to last til '91, but it seemed too overkill to have Fascism fall in the late 70's as I was expecting it to last til the 21st century.
The earlier fall of the Soviet Union makes sense as they had far less gains at the end of WEorld War II with more losses, were unable to have the massive success in global revolution they had in the OTL 50's and 60's, faced the brunt of a united and fervently anti-Communist fascist and democratic world, had Stalin live longer, and suffered the worst possible diplomacy by choosing to ally with Arab Nazi's. All of these factors lead to it making sense for the Soviets to fall.
In Contrast we have the Roman bloc who has so great success that the Warsaw Pact could only dream of, dominated the oil markets through their cartel, had powerhouses such as Italy and China, most of its members were loyal to the ideology with no great domestic horrors (though strong exceptions like South Africa and Portugal), landed on the moon, were industrial titans with a mostly open economy. Yet despite all of this after one bad war in Ethiopia the Roman Alliance just suddenly collapses with the structural integrity of a straw house and become democratic without hard opposition.
Sure Ethiopia was a bad war with large deaths and a new bad reputation for Italy, but having the root of Fascism's fall lie down to just Ethiopia and literally nothing else when they were riding high just makes the fall seem fake and forced. Was this a good outcome? Sure modern day TTL is definitely better than OTL, but I don't think the victory of democracy was earned or realistic. It would have made more sense to have the Cool War continue to the new millennium or at the very least have lots of other pressure points mount onto the Roman Alliance besides the bad handling of Ethiopia.
