As for
War Wind 2, from what little i played.
The developers decided to completely rethink the whole system from scratch and the result is not so bad. They streamlined a lot of things that were annoying about the first game, i think in a good way.
Now you finally have the ability to change the stance of your units, no more autistic reactions towards the enemy attacks.
Healing process got simplified, your wounded unit just need to enter the lab/medbay to get fully healed.
Bio-upgrades got simplified, you now have three "packages" of which you can install only one. But they also added skils, which you can rise on certain units from your main building(stealth is now a skill). However, we lost that cool paper doll which showed your installed bio-upgrades, a huge shame me say.
You don't need to learn spell by spell on each of your spellcaster anymore, just rising his skill is enough.
You don't have inns anymore, now you need to recruit from the civilian population. There is even a special persuasion skill for a certain leaders to cut the recruitment cost. I don't know if they respawn or not.
Oh, and they the changed the way you acquire the upgraded version of your units. You needed a certain number of the simple version of the unit and sometimes a reasearch in the first one. Now some of the recruits can be born with the potential, meaning that they will automatically become an upgraded unit upon the training. Gunny serg. instead of a marine grant, Sham'li Cavalier who can mount boncas instead of the defender.
Races now have a different vehicles and you can now burn down the forests and deny your opponent resources, yay!
Now the campaign is having some branching and you get more of the various interactables like merchants and stuff. It's also nice to see some familiar names from the first game pop-up.
^This guy is not lying, Wenda of Ohio is a tough one.
The alien setting in both games makes me wish we had an rpg in it. I don't feel like the humans isekaing into Yavaun ruins it or anything like that. I like both the descendants and the marines, they have character.
But you know what faction also had a nice character to them? The Obblinox and the Eaggra, they got shafted the most during the merge into the Overlords and the S.U.N. Just as an example, the Eaggra druid is now an upgraded version of the Eaggra ranger. Meh, is all i wish to say to that.
Obblinox mage is now an alchemist who can craft potions, and both human factions have the same inventor/techie "mage" who can craft useful staff like armor.
But for some reason i lost the interest to continue, i guess i got burnout from the first game and the sequel is not different enough for me. Oh well, but it was also fun while it lasted and trying this one at least was worth it.
