While the project started as a Age of Empire game.
It is quite clear the Devs did not have the Intention of making another AoE.
They clearly wanted a new vision for the game and try out new ideas.
So much so that during the developtment of the game, it started to diverge so much from the Core that makes AoE1 and AoE2.
That requested for it to be its own Title.
That way, they would have further freedom and avoid heavy backlash from expectation of long time AoE players who expected AoE3 to be more in line with AoE 1 and 2.
Now that Backlash did come quite heavily when AoE3 got released. Feeling like a ancient relic my self when remembering the release of AoE3.
It was enough for me to be discouraged at getting the game for quite some time.
As most of my friends and class-mates at the time who were quite into AoE2 had wrong expectation of AoE3 and got super disappointed.
Now I did get myself a copy of AoE3 later on when i got myself my first fully fledged gaming PC. But i never really got into it.
As I was pretty preoccupied with other games especially WoW and SNES emulators at that time. (Yes i know, ironic i used a expensive gaming pc for that, but it was mainly because of BF2 in lan parties)
Now I later seen AoE3 and I think it looks great and interesting enough that i might give it a proper shot one day.
And it is great the devs tried out new things and concepts.
But i feel for AoE4.
They hit the nail in catering to both fanbases.
Me who comes from AoE2 side of things.
One of my long time friend who had his AoE background from AoE3.
We both quite enjoy AoE4 thinking it brought good game ideas and designs from both things.
While its certainly more leanient towards AoE2 style.
Its has enough AoE3 concepts incorperated that AoE3 players dont feel fully alienated.
Now there is many more elements they should have added or could have added.
And there is more to come such ss the complete naval rework.
I think AoE4 has done great at being similar, yet unique enough to be a seperate game from AoE2 and 3 and not a direct competitor.
