Although I have low hours on steam, I've played hundreds of hours on Xbox, and the Microsoft store version of this game. (I have game pass so that version comes with it at no cost)

So you might ask, why would I buy this game again, on steam? To support the devs.

They've put in a lot of effort to get this thing to as many gamers as they can while fixing their mistake with the initial launch.

Is the game perfect? No. There are bugs and annoyances but the team working on it over at 343i is hard at work adding new content while fixing bugs!

I am one of the few gamers who completed all the achievements for the game before Halo CE hit steam (halo reach came with more achievements and launched on pc and xbox at the same time) and I have to say it was a long grind, but well worth it for my shiny Halo MCC trophy. (steam vr trophy)
