I still feel the series is very playable. Obviously MGS1 will be dated in graphics and the gameplay isn't up to par, but at the same time, it doesn't play nearly as badly as something like Syphon Filter would play like now because there's really no normal aiming like a normal TPS (outside of 1st-person sniping). You don't even move the camera with the right stick (same with MGS2) and the radar handles the function of seeing what's ahead. Aiming in TPSs really didn't come into their own until last-gen and MGS was always doing things its own way so it kinda bypassed the humps of the TPS genre. Starting with MGS2 the controls do get complex (like having to slowly release the fire button to lower you gun), but I wouldn't call them clunky or bad as once you learn them, you'll never die because of the controls. MGS3 was the game with one major problem control-wise, they got rid of the radar (due to being a prequel thus not having that radar tech) so you'd have to constantly go into 1st-person to see ahead; however, Subsistence fixed that by adding a normal free look camera (which I'm guessing would be the version in the collection). The CQC controls are very complex at first but they have to be for the amount of stuff you can do like grabbing a soldier to interrogate, to choke out, to slit his throat, to slam down, to put C4 on him, etc. MGS4 is the best controlling game in the series and best controlling TPS IMO. Like I said how TPS aiming just didn't feel quite right until really last-gen, MGS4's aiming is as tight and smooth as I've ever experienced in a TPS (and TPSs are kinda my favorite genre especially for online shooters). MGS's controls are more complex than most TPSs because you can do things you can't do in other TPSs like you can aim in 1st-person and lean your character left/right (in MGS2 you can lean up, tippy-toe basically), what other TPS allows that?! MGS5's controls are just as smooth but they do take out quite a few advanced maneuvers like leaning so MGS4 still has the best controls for any TPS. Lastly, MGS5 has an contextual cover system and contextual cover systems just aren't the best because contextual controls of any kind will get you killed from time-to-time.
