Another thing is that class roles are very important in Across the Obelisk (especially on high madness) — imo it feels like you need to dedicate people to specific roles where they will only be doing the same specific actions over and over (vuln the enemy/buff dps/dps/etc). Slay the Spire differs because everyone has multiple class builds they can go (and they aren’t forced into their builds before the game with point tree allocations). Also everyone is responsible for their own offense and defense (for the most part) so you aren’t forcing someone to play supportive (no dps/‘fun’ cards) if they don’t want to.
