I've seen some pretty cool things in all of the intersect games I've tried. It's not a matter of (Oh another game is doing it), because most games have already done it and many have mastered it and profited from it.
So what makes an Intersect game stand out? Retrofitting. That certain type of nostalgic, which is our demographic audience. Gamers who love the games of the early 90s/2ks. Not complex with 1000 hotkeys and 100 huds.
So feel free to take that idea from a popular game that you like, twist it and fit it inside your project, it's gotta be fun for the developers first imo, because what would the developer think when they begin to implement it? *Oh I don't like this idea but I'm gonna add it anyway?* Who would do that LOL?
Bottom line, most players will like any items that are + their current items, any spells that are + their current spells, any maps (even the blank ones with 1b gold spawn on it), generally they'll love any story that give OP rewards, cause who actually reads? Engine updates that are convenient towards their overall gameplay experience.
Oh and quick tip: They want all of it at ease. Players don't want to spend days farming something that another could get in an hour just because of random. They don't want to spend months getting a level, because botters/macros can do it in days. They don't want to PvP because level 100s hard camp zones. They want end-game ASAP, and if you don't have an end-game - Where's that new update? Negative review and uninstall.
I'm kinda trolling but actually, low key not too far from the truth either LOL.
TL:DR Devs - Make the world you want to live in, because you're the one truly living in it. Developing a game is not easy, even if you have a team. A lot of time and dedication is required. You will burn out, you will take long *** breaks. You will not answer every players question. You will enjoy sleep and playing other games more. If players join you, then it's a great world to them, be proud of that which you've created and the fact that people have seen it and tried it.
If not, then you'll have to find that negative review and see what went wrong and change it.
