This is my feedback after fully fixing 2 Mauses.
Beautiful tank model with ton of details, that is not worth repairing again unfortunately.

Problems:
- Framerate issues since patch (i7 8700k, 3080RTX):
1. slight decrease overall
2. 1 maus in garage is causing fps drop
3. 2 mauses are more significant
4. automatic Xray vision during part mounting with 2 Mauses in garage = massive FPS drop to 5-10fps

- Realism vs boredom
I can understand why engine has so many pistons, caps and other parts. but installing them is chore.

- 200 screws for gearbox covers
Really? Same goes for some other parts with 30 screws ... this is just too much.

- Manual repair is difficult.
Some areas are just not accessible without full dismantling of tank: some wheels, ammo boxes, few parts under gearbox.

- Outsourcing repair
Why is it so much more expensive and why it takes 60 seconds again?

- Maus sale price
Selling 1 mouse generates more profit than fixing another 100 tanks... This cannot be real.
I have 6.500.000 money after playing for 50 hours and fixing 100+ tanks and owning most of blueprints. But selling Maus generates 1.500.000 now ...
