any other games they do like? what works for one 12 year old won’t for another.

Menara - cooperative dexterity game, where you building towers Legendary - Marvel Superhero deckbuilding . “Semi” coop, but if you tweak the difficulty, the focus is on coop Flashpoint:Fire Rescue - Firemen. rescue people, fight fires.
Pandemic/Forbidden Island - this is the ‘classic’ coop. it’s a little puzzly for my tastes, but it’s popular.
D&D Adventure Games - Wrath of Ashardalon, Castle Ravenloft. alittle older, but scratches a coop dungeon crawler itch.

my son (11) really enjoys Aeon’s End and Spirit Island.

Menara is what we graduated to after Rhino Hero Super Battle. It’s always impressive to see on yhr table.

Have you looked at the expansion at all?

We moved to Menara after Rhino Hero Super battle. It’s significantly harder, but it shouldn’t be to difficult to tweak it if needed

As an alternative, I’ve been 3d printing bases to differentiate plastic miniatures. Similar to the bases in something like Argent or Blood Rage.

Obviously not as pretty as painted minis, but significantly easier to play with

My son is 12, and hasn’t expressed any interest in Undaunted. But he really enjoys Aeon’s End and Warhammer Invasion. WH:I is going to hard to find. Aeon’s End is a co-op deckbuilder, that’s pretty thinky and really leans into the coop aspect of things.

I have it sitting on my kitchen table. I’ve punched and organized since it came, but I haven’t played yet.

I’ve seen the complaint about the rules a couple times now. That it really assumes you’ve played Star Wars Rebellion, if you haven’t the rules aren’t quite thorough enough

I’ve played a lot of Betrayal. I play tested it at AvalonCon back while I was in high school.

It’s very random, and has the potential for some really great games and some real duds. I know in the later editions there have been efforts made to tighten up the scenario balance, do maybe things are better. But From my experience, maybe 1 in 3 games has been ‘good’, 1 just meh, and the last a steamroller for one side. So many of the scenarios depend on thr size of the house, with too large or too small of a house making it unbalanced. Or specific items being useless or over powered. And many of the scenarios have pretty loose rules.

As long as you understand that, it’s a fairly light game that can have a decently large group working together.

I’ve enjoyed my copy, but there was a stretch where it was OOP and going for big money. It wasn’t worth that, but for a regular in-print price, it’s fine.
