I really hope
@Morrus and the team don’t feel constrained by this mentality.
Make the game you want to make. Rename it if you need to.
AiME removes stuff and experiments with sacred cow areas of the game. It’s a great 5e powered game.
Playing it safe won’t get you anywhere.
If it is not recognizable as 5ed, it simply won't sell. Critics will make it go down the drain and I want to avoid this at all costs.
It is not that I want or that they want to play it safe. It is supposed to be a crunchier 5ed with full retroactivity. For me this means clarification of some rules, addition of rules/class features/spells and others of which you can either take or not. Take My BBEG mod for example:
Single encounter big bad guys (BBEG and Daily Solo)
1) *Add 1 feat/ASI per 4 CR (save the first four) (not for solo encounters, end bosses only)
2) Add 1 legendary action per PC above 4. (if none, you can add one attack or keep it at no legendary actions)
3) Multiply HP by 1 +0.25 per PC above 4.
4) Add 1.5 AC (round up) per PC above 4.
The players never see the difference between the "official" and the modified version. I created it because my groups are bigger than 4. BBEG have a lot of trouble against 5 and 6+ players strong party. With this, it is fully recognizable as 5ed, and it is not hard to retrofit a BBEG to its original. In fact, it can be done on the fly. This does not take a lot of space and can be done under two minutes. I am currently reading MOoT and even the Mythical encounters will benefit from this.
The "*" is simply because I count class features as a feat too. Depending on the CR and Type, I can even add a 20th level class feature if I deem it worthy/interesing/surprising. If I want to make a solo encounter that is not a BBEG but that should be a challenge; I simply do number 2 to 4. And again, it works, people looking our games from the outside see the fight and are ready to swear that the BBEG was not modified unless they watch my notes. Because I am often with the BBEG entry in the MM as a reference. And just doing number 3 and 4, if your players are a bit too weak and you feel sad for them, is and can be enough.
This is a simple example of what Enworld could do in A5ed. This would be relatively minor addition, but with a big impact. And yet, it will still be easily recognizable as a 5ed. If they want to take this as a basis for they own version of my rule, I give them permission right here and now.
There are many possibilities that can be done. But everything should make a crunchier 5ed. Not create a new entirely different game.
