Terminator Resistance is enjoyable, at least for this big fan of the duology, it services fans well and handles the old material right (attention to detail like the sounds, obscure Skynet machines like the Silverfish). Game runs like it is from a few gens ago but no biggie IMO especially considering the studio was doing its best with a shoestring budget. I'm pleasantly surprised by the side plots of the seemingly generic side-characters, sometimes it got a bit Cormac McCarthy-ish.
My nitpicks are, I don't want another special but ironically generico protagonist (another American soldierino who will change the tide plus time travel subplot), I'd prefer just an average Resistance soldier with no special destiny, preferably from the third world which in the T1 and T2 fluff did comprise most of the Resistance because those parts got underlooked in the initial (Russia-US) nuclear exchange that decimated the leading military powers.
Another would be, while the T-800s are fucking lethal and in close to medium range engaging one usually results in a very swift death (sniping is different) and this is appreciated, I don't like how they later form the main infantry (and their AI is pretty dumb).
This is nitpicky but like in the fluff, IIRC, the Resistance initially encountered the T-800s as a new form of infiltrator, harder to spot with the fleshy covering, they did not initially see naked T-800 endoskeletons, IIRC this occurred only in the ending parts of the war when in desperation Skynet had to unload everything it had to defend itself, as seen in the T2 intro.
Older dumber Terminators, like the T-600s and others could have composed the main infantry, still physically hard to kill but with an excusable lack of intelligence (I appreciate how dialogue alludes to earlier ones with rubber skin). T-600s with decaying rubber skin and "off" proportions/movements would look awesome like in Terminator Salvation.
T-800s, Infiltrators with skin or endoskeletons, should be rare treats - like mini-bosses or something. The game does have a plot-significant Infiltrator out there stalking your character and it is portrayed as savvier and more lethal than the naked endoskeleton, and is the closest thing to a boss thus far. The Infiltrator is portrayed as something new and a big deal. But I am kind of annoyed that this tougher one is labeled as a T-850, since in Kyle Reese's timeline T-800s were supposed to be the newer deadlier sneakier cyborgs. (I know Arnold in Terminator 3 portrayed a "T-850" but that's a different timeline and there the 850s are not just sturdier but have highly explosive reactors, maybe useful when units get taken down so they can vaporize everyone else with them)
I guess the mook AI can be explained by Skynet inputting different commands and settings to T-800s, ones with special missions rather than average infantry duty can be cannier - T2 canon does specify T-800s can be switched to read only or read-write where intelligence grows.
In the novelization the sheer advanced-ness of the T-1000 was something Skynet itself was unsure of, because it was possible that the T-1000s' intelligence would surpass it or make it hard to control, and Skynet only used it as a last resort.
