Hi, (mainly) AoE 2 player that kinda fell in love with AoE 3 last year here - I just want to say that I absolutely feel and share the frustration. AoE 3 essentially became my 2nd favourite game right after AoE 2.
I want to suggest, instead of review bombing games (that will have minimal impact as Valve still reserves the right to exclude excessive negative/positive reviews from the overall score), you should instead campaign players and especially content creators from other Age games to pick up AoE 3 in solidarity and bring content for it, even if it’s just for a couple of videos or streams.
Tbf, this is a weird comparison, but back in 2021 when MS announced that they’ll take away ranked Deathmatch in AoE 2, people that normally would only play the standard ranked mode picked up Deathmatch as well. They even came up with a couple of Hashtags such as #SaveDM or #SlideIntoDM
The result: Deathmatch was initially taken away but returned some months later although only in ranked lobbies.
If you show WE that there is still a lot of interest in AoE 3 + you can bring in new players, they can’t ignore you.
Looking for scapegoats to put the blame on and blindly flaming won’t help, unfortunately.
