You can't go on Halo MCC and compare the previous games with Halo 5 haha... They are all literally the worst ports of the game. Besides that, there are a ton of other things that made those games better than Halo 5 that aren't present in MCC like clans, playlists, working ranks, correct matchmaking, etc. And how you said problems like hit-detection were a big issue for you, unfortunately these games don't have the original games hit detection. Literally all of them except Halo 4 are worse than their original counter-parts.



Halo CE had a ton of problems and there are still some things wrong from the original version because it's using the PC port.



Halo 2 on MCC is the VIsta port and that's why they needed to patch the hit registration in Halo 2 classic because it was just soooo bad. So I know exactly why you feel like you can't hit anyone in these games.



Halo 3 was fine on here with exception of some of the sound issues that still happen. But like I said, there are a ton of other things that made Halo 3 great. Like the progression system, the working ranking system (same for Halo 2), theater mode, Bungie's Favorites and the File Share system, a better theater mode. The hit registration is also a tad different.



Halo 4 is.. Well, okay you got me here lol. Halo 4 is bad regardless.



All in all, these games weren't true to their originals, so it's kind of off base. You had to play the actual original versions. Your opinion could be the same, it could be different. Just wanted to point some of these things out. :)
