Just like "Shadow Tactics", this game is another great entry and homage to the tactics games of yore. Between the two mimimi put out there, it's hard for me to pick a favorite. This game sees a lot of quality of life improvements vs their last game, though there are fewer "high points" in the story, so if you haven't played ST, the lower price means a better deal is to be found on that game vs this one.
However, after playing the deluxe edition of this game, I would say that this is in fact a wonderful game that I often struggled to put down. The characters and their various abilities are extremely fun to use, the maps are beautifully designed, and the systems in place to make sure that the game is fun are once again, amazing. If you like tactics games, get this one. There's no reason not to. The season pass is by no means required, but all the missions within the pass are good, and you're going to want to get it because more of this game is never a bad thing.
I have been playing these games since the original Desperados came out, and I can say that this is the desperados pre-sequel I have been looking for. But while sound design and graphics seem to be improved since shadow tactics, the set piece moments and story seems to be a lot weaker this time around. No cool mission in the middle of a warzone, no epic samurai poem (or equivalence) and hardly any motivation attributed to the villains of the game. And why are the characters a comedy act this time around? Granted D2 made a mockery of the original cast, but in D1 the characters all behaved like adults, were intelligent, and always just worked together professionally. They were cool people, in D3 they often behave like teenagers.
But overall, a great game. I can't wait for the next tactics game mimimi releases! No matter if it's a continuation of desperados, shadow tactics, commandos, Robin Hood, or some kind of fantasy or sci-fi, or whatever else ethey do, I'm sure It'll be great.
