The thing is that everyone's tolerances are different. It's like reading Trip Advisor reviews, you might find a few for a hotel you like the look of that give it 1 or 2 stars but check out why and it's because there wasn't a maid coming to turn down their bed every single day at 5pm, or because the hot water in the shower got really really hot if you turned it all the way, which steamed up the mirror, and they expect heated mirrors in hotels like this.|
So, utterly ridiculous subjective reasons, then
TA forums, like most on the net, have their fair share of utter tools who cheerfully write off entire games because they can count the pixels in a character model, or the shading isn't exactly the same as that on their monster PC gaming rig, or it doesn't play the Action Cam every time (which actually it doesn't do in the PC version either) or it stutters when there's 5 enemies and your entire team on the screen simultaneously, or it crashes every time a cut-scene plays.
Only one of those would annoy me...
So it's impossible to tell, which is why it would have been nice if the internet's leading iOS games review site would have taken the time to actually try this expensive AAA game on every iDevice they could get their hands on before posting their pathetic 'review', which is actually just a glorified affiliate link.
