I’ve been revisiting anno 2205, infamously the ugly duckling of the Anno series of RTS games. I don’t mind so much the fact that it’s different, lacks customisation and random map generation - I’m bothered because the game is so slow to progress through on challenge settings, and it feels like a game designed just to artificially waste your time; in other anno games, you can always pull tricks to dig yourself out of economic crisis - selling off assets and surplus goods, completing quests for other parties, or taking loans. 2205 is very very confined in terms of what you can do to financially recover in the early game and forces you into a lot of military events.
Destructible walls. It’s possible to destroy some walls, but that is not in the manual nor hinted at in a classic way (discoloration or cracks). You can complete the game without knowing that. It simply did not occur to me to throw dynamite at blank walls.

But you need to destroy a wall to get to a fairy puzzle.
Invincibility toggle is nice to have, but even more of a statement of how bad the balance is. (Didn’t need to use it though - found an exploit to instakill the quarry boss :)
