I only have one problem with the premise: I was w/out internet for several hours today, and spent that time playing D: OS 2. While it's not Apples to Oranges, it's not the same either, more like crab apples to green apples.

1. Maybe it's Skyrim? Basically the same color pallete.
2. Yep, that's the same.
3. EA, although I'm not sure that will change, but if they want you to meet these comps for EA, there's really not a better way to do it. Then there's the whole thing you go on to point out later with the boat/ship similarities? Over how many thousands of miles do you expect the wreckage to be strewn, considering we teleported in, and then crashed? I didn't see anyone bailing off when we do see the ship in the opening cutscene, did I miss something?
4. Too many games to list for this, including a ton of MMOs.
5. Were you perhaps expecting to loot BiS gear for you and all your comps before level 5?
6. this, and 11, 12 and 13 are the same thing? Maybe I was playing Tomb Raider recently, and noticing all those empty bottles, and gas cans, and empty cans to make grenades out of...
7. At least "realistic", depending on the environment.
8. I hate to be the bearer of bad news, but Backstab was in the original BG. It is also in most iterations of DnD games, and other games with thieves. NWN has Assassinate, and it can even be used with a ranged weapon.
9. Yep, that needs to be fixed, I love my rogues, and I want them to be rogues.
10. Oblivion, and Skyrim say hello, off the top of my head. With the added bonus of BG 2. Sorry, this isn't a Divinity Trope, it predates Larian. Still, kinda tropey, but it is what it is.
11-13 covered above.
14. Again, Oblivion and Skyrim say hello.

I'd go on, but frankly, I can imagine that the list will continue in this fashion, where there's 2 in 14 items that I can say, yeah, that's probably based on what they've been successful with. With the rest being a definition of trope before Larian ever opened their doors. Going on a spree of "well, that was in this game, and that game" doesn't do anyone any good when there are a lot of other games we can point to that have the same things, and some of them are far older than D: OS 2.
