My dream Gundam game is an Arcsys fighting title featuring MS from every series, each animated in the style of their own show.
In which the OG Gundam is actually a secret character due to the QUALITY animation of 0079 making his moves extremely janky and erratic; with his form constantly changing shape even while standing still.
A more realistic dream is Battle Operation 2 - AU Edition.
With zero latency problems and actual balance. Also better gacha rates.
