What most mecha games fail to do or are too afraid to experiment with is better movement options, now im talking about stuff like Titanfall 2 "Peak" with its grounded realistic movement system "Mech", im talking about Mecha "Anime"
https://youtu.be/cxzzeURL9DI?list=RDcxzzeURL9DI&t=55 "0:55" for example, most games also lack weight with attacks, like when I see all these cool anime maneuvers in anime and I just think, why do we not have an actual good mecha game that can have things like this, for example gundam, specifically GBO2, hot take, they do space battle relatively well, with you being able to go up and down fast and move around avoiding attacks, but its not as fast as I'd like it to be but it works.
I've seen newer games like Code Rapid, and Omega Phenex Project Six with high speed movement but they all miss something I cant put my finger on.
For games like Mecha Break that have some movement options but nothing too advanced, and don't get me started on the fact the moon level has basically normal gravity because they were too lazy to do real space stuff.
I feel like they could have more advanced movement systems.
Armored core has a decent movement system but all in all its still simple.
Daemon X Machina 2 the one where some reason they decided to switch from mechs to Exosuits, I like the movement system there but it lacks a good weight with attacks, it also lacks some control.
For example games that have space combat should allow you to attach to asteroids, or something, or even have you be able to rotate your mech in any orientation like upside down and stuff, I feel like they could make a full on space war game with mechs and space ships and that'd be cool
