Listen: if you look at the numbers and the comments about tournament sponsorship for AOEIV, it clearly suggests that AOEIV is going to be the main AOE game out there for quite some time. The Twitch numbers haven't declined from around 20,000 so far, the tournament has got big interest, there are lots of professionals from other games coming to play it.
I believe that AOE2 is a better game, but I don't think AOEIV is a bad game and I definitely don't think that it is just going to vanish. Everyone who is honest says that AOEIV is a fun game with huge potential if the many problems are fixed. If you love AOE2 the best thing is to think about how best to manage AOE2 being second, much as AOE3 was for a long time, rather than complaining bitterly about how streamers have abandoned the game or 'betrayed the community'.
I also think claiming that AOE4 is simply an awful game is actually very counterproductive to AOE2's long-term health — it implies that AOE4 is nothing to worry about because AOE2 is such a classic it could never have a competitor. I think we have to think of AOE2 as in the long-term approaching the AOE3 predicament: (generally) good game, small community, little money. How can we stop that? Is there even anything that we can do to stop that?
AoE4 is not a bad or an awful game. But as you say yourself, it is not as good as AoE2 is. I dont see its huge potential but this is smth we are going to see how manifests in the future. I think the AoE4 hype right now is more than normal despite I already see lowering numbers of players. Im sure if it wasnt called AoE it wouldnt get even half of the attention. While I agree it will stay up there for quite some time as major title of the franchise the reasons for this are not because it is "such an unbeliavable game" but MS policy to push it and the way alot of "influencers" behave.
It is more than understandable that MS wants to make its newest product as big as possibe as there is commercial gain. On the other hand a lot of Pro players see a potential to be part of a bigger pro scene with more money and audience. They do not want to miss their chance if this turns to be the next big thing in RTS, so they jumt the hype train. That is again logical plus a lot of them have played tens of thousands of AoE2 games. Having smth new to explore and enjoy is also good.
These also explains why it is mainly players who jump on the 100% AoE4 hype train. Most big casters: T90, Dave, Memb try to balance their content as they are closer to their core viewers preferences. I exclude here Nili who is working for MS also an expert player himself, and Lidakor who is not as successful in AoE2 and sees his big chance at the AoE4 stage.
Understanding this situation doesnt answer several key questions which lead to this "conflict" situation.
1. Is AoE4 currently better game than AoE2? No, it is not
2. Does it have potential to get better than AoE2.According to few, but unlikely to happen.
3. Than should it really be the main title of the franchise? No. not really. It is other factors we explained already that make it such.
If that is the case why are we wondering there are so many frustrated AoE2 fans. Ofc ppl are feeling betrayed and abondoned and they are vocal about that. They will be vocal to a point and than will withdraw their interest and support. It is those who are now presenting 100% AoE4 content to decide are these people important to them or the prospect of AoE4 outweights alot of their core audience who have been loyal to them for years. Does loyalty go one way or you could actually start the stream with two AoE2 games to get your fingers going. Or may be end with one AoE2 game to keep you mechanics in shape for the comming KotD4 and show ppl you actually care bout AoE2 competitions.
