I'd almost agree, but the new XCOM games[0] get quickly boring to me because of their linear tech tree progression aspect. That is, all the weapons you unlock over time are strict improvements over predecessors they replace. There's no increase to the number of options or tactics - you unlock laser weapons, there's no reason to ever bring in regular firearms to the fight. You unlock plasma weapons, there's no reason to ever use lasers again. Etc.

What I'd love to play is a game like XCOM, but where the tech tree is broader than you can cover in a single game, and where options have tradeoffs - so e.g. it could make sense to have a squad where one soldier is carrying a plasma weapon, and everyone else carries regular rifles, because tactical considerations make it a better option.

(Also one implication of this I didn't like in terms of role-playing: firearms are our weapons, laser weapons are our weapons made from reversing some basic science off alien tech, and plasma weapons are just their guns modified so humans can handle them. I always felt there should be a way to make lasers ultimately better than plasmas, based of my favorite trope of humans beating alien invaders with smarts and sheer force of will.)
