I posted this on other forums, but TW:W makes me actually really concerned about the future of TW, precisely because of how much of a refreshing change of pace this was.
See, when TW:W was announced and people got upset because it was "fantasy crap" or whatever, CA was quick to assure people that they were still working on historical IPs, and that this would be headed by a different team. What that essentially means is, it's possible CA didn't infact learn any lessons from R2 and Attilla, and the improvements we see are isntead the result of a fresh faced group of devs looking at things from another angle. And since TW:W was confirmed to be a trilogy, that experince may not filter to the historical team for quite awhile.
That said, I'm loving this, AI's doing fairly well in battles tactically compared to previous games. I've seen them properly flank, do scouting runs when I've hidden before pulling back, be annoying assholes with cavalry, and so on. I've also seen them lose their shit and just break and spazz in place, but that happened all of once in my 30 hours so far, so I'll let it slide. Light Wizards are just pain machines, and tbh I've always been wishing for a rennisance era TW, and the Empire scratches that itch well enough. Seiges are meh because the one wall thing, but from a mechanical standpoint I can see why they did it, as the post wall part of seiges were always just a horrible streetgrinder where you sat at max speed waiting for your units to eventually break the baddies. Same with town battles, I do prefer the field battles to them, but it would've been nice if the town was at least in the background just past the battle border.
Also nice to see units finally have weight and momentum again. Having lines actually crash into each other isntead of blend together like a bunch of bouncy balls is great fun.
Agents are still awful, but that's been the deal since at least Rome 1, so I've just given up on it. Least I can train them by having them battle instead now so I don't have to assassin fail grind.
Can't wait for Brettonia, which is all but confirmed to be the FreeLC faction they've promised, as there are bits and peices of campign files still in the game build, such as diplomatic response messages for a Brettonian player, plus of course the fact they have a unique roster already.
So in conclusion, both reasonably looking forward to the inevitable DLC and the rest of the Warhammer Total War Trilogy, but at the same time concerned about the future of the historical games as a whole.
