I love how the BETA looked, and all the in game content we've seen from anyone playing. I guess what you have to look at is the over-all feel and want of the gaming industry when it comes to FPS. Look at all the FPS's that are making money. The look of the guns, the noises, the feel of the game. It's all meant to bring you in and make you feel like your there. So it looks the same, feels the same, but it's what makes money and allows us the end user to enjoy it. The Gaming company needs to make money, in order to make the game, that we consume and play for hours on end, day in and day out. Again, it's a game meant to be played and enjoyed. We have a FORUM To voice our concerns that is monitored and in that, changes will be made and tweaked.
I remember when Halo Reach was coming out and played the BETA for it. I loved how amazing the grenades where in it. Not to weak but not to strong and I was able to enjoy the game without dying consistently. When the game launched - I found out the tweaks made, where not that great but did it stop me from playing no ? Why, again it's a game that had more than one aspect to it and I learned to enjoy it. It's why you play games, to dominate and control.
In essence, If it looks like "Call Of Duty" That's an opinion everyone is entitled to them. But It's Halo and in that it's 343 Who handles it now. They're going to do what they do and what Microsoft wants in the end. If we voice our concerns and where heard then changes will be made. Enjoy the game, and don't think into it to much because your not going to enjoy it the way it was meant to be enjoyed.
