Ugh.
Bioshock 2 has the worst damn registration process when you buy it from steam. With every other steam game, you just purchase, download, then play, but not bioshock 2. You have to register it and it asks for a serial. I didn't buy it from a counter, so I had to go through a 3 day process to email the security company proving I purchased the game in order to get a serial. So I finally got that in, and the game finally launches, but I can't play without a Windows live account. WHY HAVE A CONTENT DISTRIBUTION SYSTEM INSIDE ANOTHER CONTENT DISTRIBUTION SYSTEM? THAT IS THE WORST FUCKING IDEA EVER!! Anyway, then I had to register an account, but it turns out that I need to egister another account because the process somehow halted. Now that I have that out of the way, I thought I could finally play, but no. It had to spend 4 hours downloading some update, then re-register my game then register again through Windows live, then ugh... I just want to play this game.
TL;DR This is a nightmare to start.
