I may be an outlier for most forum users, but I've been happily playing pretty consistently since EA dropped last year. Between Multiplayer and Singleplayer both, this has been my main time sink as far as gaming goes for about a year now. I have had my skill stretched in the crucible of multiplayer, and had a ton of fun in the sandbox of singleplayer. The periodic updates give me enough to be excited about and generate hype for what's around the corner.
I won't pretend there aren't problems or that this game COULDN'T BE so much more (Which is true for any piece of software, or any human endeavor, right?). Dev times feeling slow, bugs popping up repeatedly after being squashed, and imbalanced/unfinished mechanics will drive anyone batty after enough exposure. But I personally am really grateful to be able to play this game, and am optimistic about where it will go, no matter the pace. Your points are valid, just remember to take the good with the bad, lest we fall prey to a bitter existence in a hobby that is meant to make us happy.
