Ark Nova, every game is slightly different and requires tactical flexibility.

Hansa T does as well, though some games play similarly, really depends on who is sitting at the table to shake up the metagame. I won my last game without taking any privilege and only taking two upgrades(actions 3 and book for another merchant).

It's fine at 2, but having more players to compete for objectives and alien spots is more fun. If you want to teach the game 2 is probably fine, but I'd always seek out more players.

My favorite auction game is the Estates if that tells you anything.

It's got
>card denial(digging/snapping)
>action nerfing
>money drain effects
>card stealing
>action stealing
>player controlled round length
>worker placement denial
>hard blocking on association upgrades

It's super competitive at 2 players and at 4 you can literally attack every other player at the table with some actions. It's no Hansa Tin terms of interactivity, but it's definitely interactive and you're not going to win against a good player if you aren't interacting with them and denying them resources.
