>>8357520Change it up. You're gonna inevitably run out of shit to do eventually because there are only so many big kits out there. Find the joys in smaller scales. Like, fully detailing and painting a RG takes me longer than most MGs for example. If you're dead set on giant kits though...here's some of the biggest/bulkiest in the game:
MG Deep Striker
HG Neo Zeong
MG Sazabi Ver. Ka
MG The O
RE/100 Nightingale
HY2M Series
HMM Iron Kong
HMM Gojulas
HMM Geno Saurer/Breaker
HMM Death Stinger
Hexa Gear Agnirage
MSG Gigantic Arms
Koto Sahelanthropus
Armored Core Vengeance
Volks LED Mirage with Flame Launcher
Also, if you're not already, I would highly suggest taking your time to really work on these kits and put a lot of care and detail work in. It's a crying shame to just snapfit these gigantic things, with all their sculpted detail and wide open spaces begging to be utilized properly.
