The main problem with comparing JA2 and JA3 that is very prevalent in this thread is the fact, that people conflate JA2 1.13 and vanilla JA2 into one entity.
Vanilla JA2 was also lacking in the tactical department and had similar problems that JA3 inherited from it. 1.13 pushed JA2 from the dual identity of being a turn based tactics game and a light rpg about action/adventure movies, straight into what turned out to be the best tactical simulation of squad based fights.
JA3 actually embraces the silliness of this action movie design and leans more into this light rpg side of JA3. There are still clearly worse elements in some regards, when comparing to vanilla JA2, but there is a lot of good stuff that it does on it's own.
Everyone looking in JA3 for a build-up on what 1.13 provides will be disappointed.
I wasn't and let the game surprise me and it was a good surprise. That's one of the single player games I had most fun playing in a long time.
Bullshit. I am at start of 1.13 run, it is not much different than vanilla JA2 and already tactical combat is much superior. There is no tutorial island bullshit, endless talking at start, short range engagements, blind and stupid enemies, stupid stealth systems, pod systems, overwatch cheese, blind and deaf enemies on the map that do not come to check out what is happening and so on.
