I was just going through my expansions and realizing that there are way too many gate cards. Every expansion added more gate cards. Of course, with Dunwich and Kingsport adding new Other Worlds, that was necessary. But did we really need so many more gate cards from all of the other expansions?? It wouldn't surprise me if the new Lurker expansion has more. Sure, variety is nice, but to be honest, there was a decent number of gate cards in the base game (12 of every color); it wasn't like the encounters where you only had 7 for each location. I just think that at this point, I would much rather any new expansions provide other stuff instead of more gate cards. Same with Mythos cards, unless there are some really cool new ideas to them.

Anything else we don't need more of? Or do need more of?

I think it depends on how many expansions you are running (its affecting my games alot less these days when using just one expansion at a time).

With just one expansion then Mythos cards at least are a good thing (for extra flavor to the game). Gate cards are ok if they are thematic to the expansion (although I care less on this since gate cards are to alien dimensions with their own theme).

Using all expansions tends to dilute things alot and to create a towering mythos and gate deck (yay shuffling!).

Personally I think we have enough investigators and monsters (just a personal opinion) , I would love to see more items (common/unique/spells), allies and skils not so much (ally deck gets diluted easy and skills are important to game balance).

If I could have my pick for an expansion I would love to see a solo themed big box (possibly stand alone map as well), where the idea is to play with only 1 investigator. Even if I play regularly with a group, I still crave solo on occasion.

Innsmouth was on to something: their Gate cards were discarded if you weren't in the correct OW. This would be a way to add more other world encounters without diluting the expansion ones, specifically.

They don't always have great ideas for gate cards. At one point they were using Bob Dylan lyrics.

More: Ancient Ones, Investigators, Heralds, Guardians.

These entities don't really break anything in the game, they work with everything and provide a greater number of combos and challenges. I'd actually like to see an expansion of just these!

also, I usually don't play ALL expansions at one time, usually just 2 big board expansions and 1-2 small box expansions. This works out pretty well but i also like having the variety of expansion boards to include, it would be nice to have one more just to throw in the mix...

Less: talk, more Arkham...
