The save system idea is great, if it was done by any kind of developer who doesnt release their game with game breaking bugs and crashes. I get the save system tha they were going for, and if i only ever lost progress because of a stupid mistake that i made, then that would be fine. Unfortunately this game was released far to early and so it has game breaking bugs and has a nasty habbit of crashing, causing you to potentially lose a lot of progress through no fault of your own. There is a reason that developers like this one should put in at least some kind of timed auto save system. I wouldnt even care if i was unable to manually load from those save spots, i would just like them there for when the game inevitably has a problem.
If you are going to make a save system like this then you should be darn sure that on release this system is not going to screw members of your player base over. There is no worse feeling than finally completing one of the obnoxiouse hunting missions where you are looking for roe dear (god forbid there be as many of them as red dear), and after a full night (a few hours), of hunting and finally handing the meat in, the game proceeds to crash after completing the quest. Also there is nothing else that makes you want to just delete the game and never play it again than waisting all that time. Even adding in a save after the completion of a quest would help a ton in this regard.
I think this save system idea could be fantastic, if done by a better developer who works out at least their game breaking bugs before release.
Ps: i would much rather stair at a blank loading screen than go through this annoying scene every freaken time i start up the game. It was cool the first time, and tha is it. I have now resorted to mutibg my tv and walking away from the tv until i think it is finished.
