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.
Halo was the first FPS designed to be played on console controllers rather than with mouse and keyboard. That's why it feels like shit and why I hate it.
It's also why it was so popular. Halo definitely wasn't the best shooter of the year, but it was by far the best (and only) shooter on the Xbox.
