PixelBoy: I second this opinion entirely.
Spectrum_Legacy: Achievements are as an extra feature, you know - completely optional. If they bother you so much, there is an easy fix for that, very much unlike cancer though.
Same for me - I am always happy about any optional feature in the game - I prefer local Co-op, but LAN (without DRM) and normal online (even on GOG only for DRM fans) is OK for me - as I don't have to use it (or won't ever use).
From my point of view achievements are for small children who see what they have done right now and what is left. ;)
But as several people like it, I am fine if all games would have that feature.
I have not yet spot any game where achievements would annoy me - so I am fine with them - but personally never looked at them.
The more a game can be tuned to the interest and taste of a gamer, the better it is for that gamer.
It is extremely important to have a difficulty range which keeps any gamer interested - not frustrated due to not fulfilling it nor the opposite to reach the end of the game with no effort.
And still there are gamers who e.g. demand a game to be extremely hard ... don't get that point (at least if the score scales with the difficulty level - for those needing to say "I reached ..." - we all must feed the child inside :).
And more important the controls: should be a standard to have keyboard/mouse/controller completely set and even two keys bound to the same function (like e.g. Fury Unleashed does - in several way a golden standard in respect of perfect options) ... but still choosing good defaults so that most gamers don't have to visit settings/options - controls ...
May add options for crosshair, CRT distortions, flashing, screen shake etc. - some like it, some are annoyed or even sick.
So switching some features on and off is extremely important.
Thus it would be best to just smile about achievements - even if you don't need them ... (and just smile about gamers just happy because of that feature) and similar for other options which are not in your way and not spoiling the fun when playing the game ...
We all win when developers have a feature list to make a lot of gamers happy ... this would make each of us more happy
when buying such a game (no matter what we set to be happy) ... a shoot-out about the set of fixed options of personal
taste will not help any gamer.
And asking for a missing option should not be a reason for making anyone angry ... at least I hope so.
