I think that World’s Edge were hoping it was going to be like AoE:DE - ‘one and done’. Give the community a DE of a much-loved AOE game and let it be. It turned out to be more popular than they thought and they realised it was a good opportunity to make some money out of it, which is of course fair.
I believe there at that point we get two main trains of thought. WE’s thoughts - make some money until it takes too much resource away from the ‘bigger’ projects then dump, whilst the AOEIII fanbases’ thoughts, unaware of this, just see the excitement of some fairly regular DLCs and the sign that the game looks to have a supported future.
These thoughts don’t truly clash until KotM is out where product support soon becomes quite spartan and dev chat starts getting quieter on here/Discord. Lack of communication and support to address bugs - essentially being given the cold shoulder by the publisher had annoyed the community and still has soured the community.
In hindsight, World’s Edge should have said KotM is the ‘farewell’ DLC (and its accompanying set of updates - particularly update 14.43676) - it has all the hallmarks of a ‘send-off’ update - 2 civs not cut from a completely new mechanic/art-set, but made with mostly existing groundwork, plus a ton of wider, quality of life stuff, including new unique textures/models/cards/etc to existing civs.
Then a series of bumbling, dare-say inept decisions that made the AOEIII community feel like they were being strung along.
World’s Edge is a professional business and we, the AOEIII community are customers. Some customers can be loud, annoying, a minority a bit toxic and stupid even, but the vast majority just want to purchase content and play the game they love. Like any game fanbase!
Blaming 75% of the terrible state of AOE3 on an entire community, or rather the customers is absolute madness.
You reap what you sow. You make a product to which has garned a fanbase who invests time and money with it, to then take really poor marketing and PR choices (basically keeping the third game in the background) and not commmunicating with your community, with the final nail in the coffin being the weird dance of announcing DLC in the midst of the other AOE DLC/update announcements for them to pull the entire thing - well yeah, it’ll get an entire fanbases’ backs up.
Blame is with a business. Customers invest time an money in things a business offers if they appeal to them. Customers are happy when they feel the business respects them and when the business is excited by their own product and can communicate with their audience. Business benefit from this by making more content to sell to a happy fanbase. It’s simple.
Bad business practices just alienate the customers.
