Well there's a couple layers to this. I don't think anyone can argue Halo wasn't a decent game. It was competent, had a lot of production value and didn't have any sort of enormous shortcoming. The problem is so many of players and the games industry at large were praising Halo as the second coming of Christ. I mean hell, the guy above me thought that it was the FIRST to do all these different things that it wasn't. So hearing over and over again how it's the best game EVER for all this ORIGINAL stuff got old fast, because seasoned FPS people knew there was a lot more that came before it. So instead of being the okay game that it was, fans thought it was the BEST game and people who had played more were saying it SUCKED as sort of a counter-reaction. Plus, it is true that some PC players were going to dismiss it outright, not so much because it was on a console, but because it was on a gamepad. If you were a seasoned FPS player, moving to a gamepad, even to this day is such a step down in terms of accuracy and control compared to a mouse. So it could have been one of the best games ever made, but having to play a FPS on a gamepad is still a slap in the face for a lot of PC players. Even if the game was designed for that, it still feels like playing golf with one hand tied behind your back, hence a lot of the dismissal.I see it the exact opposite. Most PC users shat on Halo because it was on console, without ever playing it. I was big into the UT and Quake 2 multiplayer communities when I first played Halo and I loved it. I still wanted to play UT2K3 when it came out, but I also held regular Halo LANs.
Besides the stuff I mentioned in the previous post, even though they're very different games, the most obvious one that hit me was Starsiege Tribes. It had a similar sci fi aesthetic, large open maps, and vehicle use. The thing about Halo is that it's sort of a milder remix of many games that came before it. There are individual elements that you can point to that came from other games, often done better and more refined, but just for those specific elements. Deus Ex and System Shock 2 had better stories, Serious Sam had more intense action, Starsiege Tribes had more tactical focus and movement control, Alien v. Predator had more innovative gameplay mechanics, etc. the list goes on. Halo is more of a jack of all trades, master of none situation. The element that Halo truly stands out as being "best of class" in, is the gamepad control. Nothing else came close to that and it truly did innovate in that area, which is where it counted for a console-targeted FPS. That's also an area that had no real bearing on the PC. Again, Halo was in the right place at the right time.Also, what games did what Halo did prior?
