HLL didn't get good until last year and I've been playing since 2018. It'll get there and the bugs are such a minor thing overall its not worth even complaining about as it hasn't stopped me at all.
One thing I did notice is how perfect the colors need to be on your monitor (calibration) to see anything. Im starting to realize that with modern graphical fidelity if your colors aren't perfect you are going to be at a serious disadvantage. I think this is why I hated most modern games.
I spent a few hours tweaking the color profile and now its amazing and easy to see people. Its a bit more work but something new to tinker with.
The bugs are an annoyance, and I'll agree that they're something that will probably improve over time. Most of them are relatively minor.
But the graphical fidelity and sound design in this game are a complete mess. The audio especially feels like a massive step backward from HLL. Guys on my left will sound like they're directly to my right, while someone firing a weapon to my right can sound like they're 40 meters behind me. The directional audio is just horrible. For all of HLL's faults, sound design is one area where they absolutely nailed it, and the difference is immediately noticeable.
I also shouldn't have to spend hours tweaking an entire color profile and practically become a professional monitor technician just to get the game's colors to look remotely correct. And have you seen the explosions? They look like something straight out of an FPS from 2002. The game is horribly optimized, and despite the performance issues, it still manages to look mediocre on a top-end system (9800x3d, 9700XT, and 32MB 6000mhz RAM).
Then there's the complete lack of bullet penetration, which feels absolutely ridiculous for a game set in the 1960s/70s. It was already dumb in HLL, but it feels even more egregious here given how much technology has advanced in the decades since. Watching a helicopter unload its miniguns into a wooden village while guys hiding behind wooden tables somehow absorb the rounds is just comical. It feels incredibly outdated for a modern FPS.
Then you have all the balancing issues, like the AK-47 being vastly superior to the M16, Viet Cong tunnels essentially being free while helicopters have an associated resource cost, and various other mechanics that feel poorly thought out.
You're right that HLL took a while to become the game it is today, but even in its early state, it felt more cohesive and polished in a lot of ways. This game feels like it was rushed out the door.
At this point, I'm just hoping Wardogs ends up being the next great FPS. I honestly haven't had much fun with an FPS since the early days of BattleBit.
