Im 30 hours into the game and biggest problems for me are:
1) There's basically no reason to use automatic weapons, except MGs.
2) Stealth is overpowered and enemies are blind. Im thinking about never using it.
3) Too few enemies even on hardest difficulty with "more enemies" option, at least in the first half of the game where i am. Im swimming in explosives because i don't use it on less than 3 enemies, so barely ever.
4) AI is retarded. For all the AI hype we still cant program enemies that can do basic tactics. At this point i don't even bother spreading my team around.
5) Night vision goggles should be a helmet mod, not its replacement, its annoying to swap depending on time of day and takes up valuable inventory space.
6) Need for 3 personality traits limits your team selection. I think the next run i will cheat myself all 3 dialogue traits so i dont need to worry about them.
7) Ugly women yet attractive men. It says that its parodies old action movies but i cant remember a single one with an ugly action chick.
With all that said, we cant play old games forever and the game does some things right. Id rate it slightly above Silent Storm.
1) I am fond of using assault rifles with mercs that have autofire skill (Pierre with a nicely modded AUG is starting to hit a lot) and even SMGs with Smiley, Len or others. Len has wasted countless enemies with a modified MP5k from the flea market. MG's are ammo sinks in comparison, and it takes a while into the game for mercs to have good perks to go along with regular MG usage.
2) True. OTOH, running face first with a bunch of shotgun tanks into a horde of enemies until they notice and you start right in their face is a valid option in this game as well. Smart pause allows to meanwhile set up machine gun cones or sniper ambushes. Battle initiation is complete bonkers, it's like a different game until the first true turn starts.
3) Using explosives because you need to?? Using explosives because it is fun! Larry, Fidel, Barry, you can do fun things with explosives. Same is true for RPG-7 once you find them. Mortars are meh, but grenade launcher are also fun (but they are noob tubes, use RPGs for coolness instead).
4) AI is quite the disaster, especially for how immersion-breaking game-ish their behaviour is at times. There's 6 mercs armed to the teeth pointing their machine guns at me. Hmmm, how about I run through their entire group, take cover behind a small stone on the other side of their position and fire a single pistol shot from there. What could possibly go wrong?
5) Is retarded. Probably a balancing thing but still retarded and annoying. Does the AI actually ever aim at our heads? At least you can still switch the goggles for free when placing mercs in battle, but it wastes your time and inventory slots. Just one more inventory slot couldn't be too hard, could it?
6) I hate that one too. Very much limits early game squad composition (the early game seems to be heaviest with skill-check and personality-check nonsense quest options). Along with a few other weird choices they made, like leadership speeding up team travel so much but we only have 1-2 high leadership characters in the entire game... We sorely miss Stephen Rothman as an alternative to Raider...
7) Lol @ attractive men? :D Generally I think there are not enough good NPCs (female or male) and some are just like copies of each other. How many badass grannies does it take to take out a WW2-era mad scientist/arrogant doctor?
Be sure to play it for a bit longer. For me one thing that works well to motivate me way into late game is the perk selection on level up together with chosing and modifying the matching equipment to the perk. Anyone who has ever placed Spike behind a .50 cal machine gun has probably had the same laughter of disbelief that I had. Seriously put him behind a .50 cal at some point :D
Strategically, the game becomes kind of dull because any remarkable attack (except some beyond-the-rule-big-event) will go through the same sectors pretty much all the time and it's almost always the same sectors that have enemies. I think the game could be improved quite a bit on the strategic level with more Ja2 style roaming patrols or the like. So you can fight them in different sectors. Not always the same spots.
