Largely because nothing happened. The scene didn't exist for Eggman to mind control Tails; it existed to establish mind control as part of Eggman's plan, so you later realize the resort is basically a mind control cannon pointed at Earth. Characters actually being mind controlled wasn't important.
That sounds dodgy. You'd think that him mind-controlling someone would've at least had more going for it, because while it established mind control as part of Eggman's plan he intended to test drive it on Sonic. Tails just so happened to move Sonic out of the line of fire and get hit by the beam. Now given how little plot was put in the game for that to be realized, I won't say that should've been important, but it just puts that into the question of how that would've went further...if that makes any sense.
The difference is that the characters still choose to take those actions. Whether they're tricked, coerced, or just mistaken, the characters still have some amount of control over their fate. Whereas with mind control...they don't, by definition.
And how does that make it a better cliche? Because as far as I look at it (as I do with a lot of things, naturally), it's a matter of how you pull it off than it is simply because of what it is.
I really would like to hear how you think a mind control plot could work.
I'm not entirely sure how I could convince you. But hey, no use in not trying.

So here's my idea. Now I'm more fond of technological means of mind control. Typically, in these cases if you destroy the source of the mind control, then the victim is free from the influence. But how about instead of having it to where you have to destroy the device to free the character's mind, destroying that device does absolutely nothing and the character is still they way the are when they were mind-controlled? As a result, it's much harder for the character to revert back to normal, because you've destroyed the one thing that could have brought him back. I'd say it blurs the line between mind control, because now there's nothing controlling the character's mind for it to be "mind control"; however, while the character is now acting on their own actions, they're still not their original self.
In Sonic's case, a Eggman captures him and puts a mind control chip or device on him that makes him loyal to Eggman. He starts attacking his friends under Eggman's orders while helping Eggman conquer the world. His friends see he's mind control and think that destroying the device will bring Sonic back to normal. They destroy the device, but Sonic still attacks them regardless and continues to work for Eggman. And now his friends have to work out another way to bring Sonic back.
That's one way you could go about a mind control plot. I've got more, but I just have a mental picture of it and it's hard to put it in words. Plus they're a bit more over the top, so they'd need more finesse in writing.
