Nostalgia factor aside, the game just clicked.
The art direction was the first thing that really attracted me to it, the game was just a lot more colorful visually, even the enhanced moves activation each character had their own glowing color while triggering.
And the second i tried the gameplay, it was amazing, the juggle physics and possibilites were superb, felt a lot more like UMK3/MKT in some way which has been like everyone's favorite MK for years globally, it felt like MK2 when playing neutral, it wasn't so oppressive as MKX, you really had to know your range to throw out moves. each character was a lot unique, the best Jade visual and gameplay design i ever seen (until they nerf her) Lot of people around the globe joined TYM, myself included and everyone was just having a blast.
And then when MKX came out, i guess ppl weren't really expecting, the formula was perfect in MK9 we didn't understood why it changed, anyway, here's to MK11.
