I didn't even realize I was supposed to use aids in the fight until Gauntlet 13 or 14.
I hated a few of them:
Cassie Cage / Jacqui Briggs tag-team
Kano / Sonya Blade tag-team
Raiden where he imitated Rain / Shinnok by the colors of his costume and his aids.
I hated the Fatal Blow one where you had to kill everyone with Fatal Blows. I thought I could use "Kombo Blows" or whatever they're called like the uppercut one. Didn't realize 'til midway that I had to use the "Fatal Blow."
I hated the Kotal Kahn one as well.
The Captain Planet tower was sweet.
In summary, some of these pissed me off; but, I loved the themes of them. I also liked how they dressed up Scorpion as Smoke and Reptile; and, Sub-Zero as Rain and Ermac in the Chameleon stage. Liked it so much I changed my main Sub-Zero to the purple costume and named the "Dead of Winter" variation "Rain." Did the same with Scorpion "Reborn," but named it "Smoke" instead!!
Geras fight was easy with the Kung Jin stun arrows and Cyrax Net with 30% health regeneration (which wasn't really used), because Geras doesn't seem to block in the final stage.
I don't like modifier fights, but I liked these because of the themes. I love themes and shit. Especially creative ones like they did here. The random modifier fights elsewhere in Tower of Time is lame though.
I forgot to mention; the Gauntlets with the stupid modifier where you froze because of the weather conditions were the worst. So annoying because even if you blocked you'd be frozen. I didn't really lose on these (I think it was the Sub-Zero section); but, shit is stupid how you can't do anything about it if you don't have a "ICE modifiers don't affect you" aid.
Anyone know how to re-roll the towers? I'd like to go back to them sometime.
