I haven't played Rush yet so I really can't compare them objectively. I think Sonic is about blazing through varied environments and finding out the hidden areas.Generally having fun in the level.What is your take thatguy?
I agree, to an extent, but you forget about the unique enemies in every new area, as well as a more unique level design featured in each zone as well. With Sonic Rush, you run through each area as fast as possible. Remember Sonic's spindash? Well, you get that, and an upgraded form of it, as well. The issue is, the speed boost allows you to run through the enemies, no damage, instant kill. Not that you really care about not using that speed for a challenge. There aren't very many unique enemies in the Rush line. They're all similar to the Gamma-type bots in Adventure, in that they stand and shoot at you. There aren't really stage-based enemies, unfortunately.
Breakaway platforms are few and far between, and the platforming is abysmal in the Rush line. In the later half of the levels, there are long gaps to jump over. However, the speed you need to run is high enough that, well, you won't have enough time the first time you play the stage. You need to memorize the timing of the jump out of trial and error, and while you may think this makes for challenging gameplay, it really just means you'll have to fight repetition to beat some jump in the middle of the stage. In the classic Sonic games, you stood nearer to the middle of the screen, and overall speed was a tad lower, allowing you to see jumps coming and make them the first time, given enough skill.
To me, a Sonic game should offer exploration, multiple paths, unique enemies in strategic places, cleverly designed pits, and strong platforming opportunities. I think that covers it all. Sonic Rush offers only speed and repetitious platforming, from that mix, which really doesn't go very well together.
