Because mecha is a genre that requires good gameplay and control design, which a lot of devs fail at, and mecha fans have gaslit themselves into thinking bad controls = MUH WEIGHT AND SKILL!!!!!

If you look at the best rated and most well sold mecha games ever you'll see that all of them have good controls and combat, even if they're weighty. People love Titanfall 2 mechs and they're both weighty but also control well.

The issue is that a shitload of japanese devs (which are the ones that usually make mecha action games for some fucking reason (the west is retarded)) can't into action games and shooters so most mecha games that come out fucking suck.

And FUCK mechwarrior.
