Across my multiple playthroughs on the 360, Xbox One, and now on PC, I still hold Halo 3 in relatively high regard, yet I still feel it to be a wholly overrated game. As a PC port, Halo 3's port over to a platform worth a damn is honestly fantastic; it runs buttery smooth, rarely ever had any sort of frame drops or any other performance issues. If you've never "finished the fight" and have a PC, Halo 3 is a must buy.
As for the multiplayer, it works, and I do like it quite a bit, but it's far from my favorite Halo multiplayer. MCC's addition to customize individual armor pieces is certainly a thankful addition (despite the fact it should've been in the collection day one back in 2014), but there are some notable performance issues on the PC port, primarily through some rather wonky latency. I'm not good at Halo multiplayer and have never claimed to be good in any of Halo's multiplayer modes, but there's some sketchy performance when it comes to trying to deliver headshots and just connecting shots altogether. 343 has addressed the latency issues and said they're working on it, but for now, the overall package is good, if not a tad flawed in some places. Still well worth a pickup.
