Most won't have played CE online as it was pretty much Xbox exclusive. H2 is where the real online push was for console users. Part of the mccs issue is using pc ports, it's something I'd like them to also fix on as it's entirely different playing a pc version when you're used to console.
I myself think this is long overdue but better late than never as they say. I'm not asking for perfection but just a huge improvement to the mcc, get that done and you'll really get a lot of faith back. I also understand the scale of the collection, you don't see 4.5 games in one together very often and I think that's cause devs know their limitations. I've also said in the past that's it's great you guys wanted to give us this but I think you got a little to ambitious on it, in short you bit off more than you could chew.Halo CE did have online multiplayer with the PC version, it was the first Halo game to ever have online multiplayer, even before Halo 2. Granted, it was only on PC so I wouldn't be surprised if some here never experienced online Halo CE multiplayer and the MCC could have been a good way to do it when MCC is fixed.
not to be a Debbie downer here but I'll be realistic. The halo player base IS split. You have people that don't want to play the newer games and you have people who wil only play the older games. The reason why mcc got hit so hard is cause that is what could've benefited those who won't play the newer games. I mean CE had no multiplayer before and H2 was shutdown before the mcc was a thing. Then you had halo 3 which had such a small pop. In comes the mcc and you see people get hyped up for it, many getting to relive their childhood, some getting to try these games for the first time ever and some that simply can only tolerate those games. So the mcc had such high expectations from the start that when it bombed it really hurt those who were into it. I think if you really improve the mcc you'll get a good portion of those people back and at least you'll have something for those who won't play your newer games. My issue was "go play the mcc if you don't like halo 4/5" when sorry to say, they are a broken mess right now. It's actually insulting to me when people say that,
I'm not expecting many to have played it online to be fair although Halo PC was surprisingly popular (and a lot of fun!). I agree with you about the PC ports, though, I don't think CEA using the PC engine is bad since the PC version was a very good port of CE anyway. The change from 30fps to 60fps may have thrown some people off as naturally, that would make the game feel different from the 30fps original.
That said, Halo 2 Anniversary uses Halo 2 Vista (PC) as a base and, I'm not sure if you ever played it, but that version of Halo 2 was a colossal failure due to a large number of bugs and glitches. The game also had some very odd changes from the Xbox version and does feel different. For example, the FOV is actually lower than the Xbox version, a trait i believe H2A has inherited as a result. In fact, Shock120 and some other modders managed to get online co-op working in the PC version and some of the crashes that H2A experiences in co-op on the MC levels (people mention Delta Halo alot) are very similar to issues experienced when trying to start a co-op game on the same level with the mod. Another bug that H2A likely inherited is the Gravemind level crashing as Halo 2 PC is infamous for having issues with this level as well.
