i dont know why people bitch about the updates.
Where do you see people bitching about updates? Someone literally asked a question and then some ppl wild guessed.
[...] how many updates other games more big than this get in one year?
On average? I've no idea. But there are some notable examples that comes to my mind. That would be Fashion Business with 8 updates in 2019
v0.2 - January 19 (1400 new arts, 73 animation clips)
v0.3 - March 6 (1130 new arts, 43 animation clips)
v0.4 - April 19 (1000 new arts, 64 animation clips)
v0.5 - June 7 (1150 new arts, 62 animation clips)
v0.6 - July 20 (1950 new arts, 20 animation clips)
v0.7 - Sept 8 (~2000 new arts, some animation clips)
v0.8 - October 19 (~1700 new arts, 42 animation clips)
v0.9 - December 5 (~1250 new arts, 74 animation clips)
or Treasure of Nadia with an update literally
every two weeks, for example.
