HUGE fan of the original. Hundreds of hours playing it. Pre-ordered this.
I suffered through the first 2+ weeks of unplayable glitches by messing around and just getting a feel for the mechanics. It was beyond frustrating.
Then, once I was convinced it was mostly fixed, I played a couple more weeks open world. By the time I got to actually play the story without any glitches, I had already lost the main thread of what was going on (audio issues ruined much of the beginning). The final boss is so silly and feels like pointless repetition and just absolutely ridiculous in the context of the rest of the game.
I also was already at such a high level that it was very easy, no challenge, to do the story and the final parts. I wouldn't have been, had I not had to wait so long for a complete game to be ready- also, no scaling for the main story is so silly! I am not a good gamer. Very casual and only play during the winter months. I found the main story extremely easy and not compelling. I would end up skipping dialogue and it felt like suffering to play.
The open world is good, there are fun parts and I can mess around for an hour here or there while I'm killing time. I do look forward to playing for short stints but then I get bored. I find myself getting bored a lot sooner than with the original game. It also is just so much easier than the original game, even on hard, and this also makes it less scary, which also makes it feel a little bit more hokey. I was TERRIFIED to be out at night in the original, as were most. Now, I won't even bother playing during the day because it's boring. I play exactly ZERO other games on a hard setting, and often err towards easy settings!
Also, no guns? That at first felt strange in the original game, but I ended up loving it. This loss is NOT made up by the paraglider, and the grapple is worse. Ugh.
The physics are good and it's a good/ok game, but I would never pre-order again, NEVER again, and it's just not up to the level that I expect from the franchise. If there's a DL3, I'll wait 6-12 months and get it on sale with low expectations.
