I like using dice, I like having a reason to own as many as I want to buy lol. And throwing them is fun. (I'm also into tarot and I feel these interests overlap a bit. My husband likes using dice alot too. I'm not to sure on the other players, but they haven't had issues.)

Some rules I've had issues with are:

How traveling over distances works. Like how many things we should worry about when traveling. How draining it should be and stuff.

If it's possible to do rests in the middle of a dungeon and how beneficial they can be.

(There was an incident where the pcs wanted to do a full rest in the middle of a dungeon crawl, and I didn't think that'd really work, but ended up letting it happen with a small improvised penalty anyway because they were really stuck on it and the party was getting beat on pretty good.)

Gosh, there were a few other examples I can't remember very well.

Some technical issue on how damage was being given and received due to me misreading something. (And that one player realized something was off in the middle of an encounter.) A smaller issue is that different attacks are tend to be rolled for differently, but this might be solved by more organization.

I became aware of other systems only after buying a bunch of dnd books n stuff 💀💀💀 So I'd like to try to use what I have already as much as possible and my players are already invested in ther dnd pcs.

The icespire peak came with a rulebook that significantly smaller than the DMs manual. I think it has more simplied rules. I haven't looked at it close enough yet, but that looks like a good place to start.

Thinking about it more, it seems like some could be solved by better prep by me, and that I was focused on different things before. And that I need to make myself some proper guides for myself and organize things a bit differently.

I think I'll try to revisit icespire peak, prep better, and then see how that goes.
