Mass effect was a pretty huge IP, it was so good it was even hard to copy by other developers.
Truthfully it moving away from what it was and trimming the fat (some RPG elements) was perfect....
Mass effect 1 was great but 2 was even better, some pinnacle gaming of this last decade for me personally.
That and breath of the wild
Granted alot of games are missing that should be on there.
DotA 2
Overwatch
Sekiro
Yakuza 0
Horizon
