Okay... The question might seem silly, but I should mention that I’m not familiar with Aion 2 and haven’t played it yet; I’m just doing some research ahead of the global launch in September
I'm asking here with a new post because it would be pointless to respond to everyone individually, but
are you worried that expanding the options means being forced to use them all? And most importantly, what "flow" are you talking about? There are some completely dead moments in Reignited Trilogy, like when you simply have to stand still and wait for platforms to line up.
I finished the main story and most of the side quests in about 75 hours. I still have all the elder dragons to defeat, as well as the invasive monsters to kill, as well as all the side stories for the secondary characters. In the meantime, however, I've been using the habitat restoration mechanic extensively to get at least one of every specie of S-level monsties (except, obviously, the three elder dragons), and the repetitiveness combined with the RNG made it all boring, frustrating, and ruined the overall experience. Being forced to press the same button over and over again for hours in the hope of finding the desired egg is simply bad game design. Not to mention the fetch quests... I already had to lower my expectations due to the poor writing of the main story, but then being "forced" to complete dozens of side quests that add nothing in terms of lore or plot and have the structure of a '90s JRPG is simply embarrassing…
