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.
It's one of those great ironies, because flight was a requested feature since the beginning and being locked into fixed flight paths left people wanting free flight even more. Back in 2006-7, I don't think most people, or even Blizzard, could predict how much it'd hurt the social aspect of the game.
That was an integral part of the game design.
Those things, like underpowered weapons for example, is something "gamers" pester about and want changed, but any good gamedesigner knows better than to listen to them, it breaks the gameplay.
Today it's worse in many games because the "annoying" things still exist but you have to pay to get around them, and it just makes the gameplay suck. IMO.
I'd never be able to find it, but back in the Vanilla days, there was an interview where one of the designers literally explained that flying was a bad idea and would ruin the game for the exact reasons it did. They knew, but someone must have overruled that.
