TL;DR: It's fun, and has enough content at launch to warrant the price (unless you are a victim of lack of regional pricing).
As of right now (no patches yet) the game has performance issues when transitioning between zones in a mission- probably because it doesn't load the assets until you get to the checkpoints. The cinematics are CRINGE and the voice acting is corny (it grew on me). The movement is floaty as if you were playing a first person game in a 3rd person perspective.
However, it is REALLY fun. Ridiculously so. What the game does bad is glaring, but what it does right is just as obvious if you play past the first mission.
The enemy variety is impressive, especially for launch. Three different factions (technically four, but robots and synths work together) that each have their own specialized units. Their AI is fun to engage with and you'll be shooting at the walls, floors, and ceilings.
The weapon customization is above solid. You have a large variety of weapons, some class-restricted (at first) and some not. Each weapon has 3 attachment slots with a ton of options. When you max out a weapon you can augment it, which drastically changes how the weapon works and there are dozens of really powerful choices for that too.
A really fun mechanic that makes missions repayable are the Combat Cards. They are similar to boosters in Helldivers 2 in the sense that each player can select one to bring. However, rather than small helpful bonuses (some can be that), they are instead game-changing modifiers that make the game harder, easier, or both. For example, rank 4 High Threat Environment increases how much damage players AND enemies deal by 100% for a 1.5 reward multiplier. Some add restrictions, give massive buffs/de-buffs, or even give you extra items on mission completion.
But the most impressive thing is the build crafting. Holy... It is extensive to say the least. I am a little more than halfway through unlocking all the medic's perks (just finished the campaign) and the amount of builds I have tried and succeeded with is astounding. It's hard to tell just what a class is capable of doing, because each class can build to do SO many things effectively.
The game has its faults, (performance will likely be addressed- movement, cinematics, and voice acting not so much), but the progression and teamplay really carry this game. It's been awhile since a game has launched and I genuinely felt like it has enough content to sink 100+ hours in without running out of things to do.
And the flamethrower you get towards the end of the game... FINALLY, someone has done a flamethrower right. The movement might be floaty, but I swear I can feel the weight behind that thing when I am purging xenos.
