Reach was something completely different from halo CE, 2 and 3. It already made an attempt to bring the series to the next generation. But as halo 4 surely will evolve, it has to stay true to it's classic origins. Reach expanded its gameplay to a more casual adience, giving everyone something for its money. But while it was still very much halo as we know it, it adjusted its gameplay to a more general group of gamers. In other words, Reach was and still is easy. To many additions were made to make te gameplay more accessible. Don't get me wrong, i love Reach, but it lacks that true halo online experience. I guess all i want to say here is that i would like halo 4 to be like 1,2 and 3.
