Badly written. Bad design.
Now onto a personal thing. I completed the game with my stats saying that I did not get wasted, busted or fail a mission. After a long hiatus, I picked up the game and started playing free roam. I began a rampage mission and due to my unfamiliarity to the controls from a long time without playing, I died. Now, when I used to die on missions I immediately turn off the DS and restart it so that my stats stay zero. But this time when I rebooted the DS, I was in a different location to my last save. I checked my stats and it said wasted = 1. How is that possible when I disabled auto-save (the worst video game invention) when I started the game and haven't touched it since. Checked the settings and there it is; Auto-save = on. Not sure how that happened, maybe a bug, an update, Nintendo generally being shite.
But no problem, I'll just load up my older save...where is it? Oh yeah the auto-save that I turned off had over-written the HARD save that I had made in a safehouse. So from completing the entire game with my stats staying clean, a stupid rampage mission death had ruined the whole game. Won't ever pick it up and play it again.
Bad, bad, bad design. A complete miss-step, Rockstar. Get rid of auto-save and statistics for how many times we die. Who wants to know that?
