-This is a great nostalgia game if you've played the first - it largely feels as you remembered it, but upgraded and refined. It was lovely to see Bros moves return in battle and all the enemy damage seemed as brutal as it did on GBA.
-The title screen intro is adorable, a group of Yoshi sit in a cinema and watch the original game's title animation unfold, only for Mario and Luigi to break through and show something a lot more, well, modern. Reminded me of the opening to Pokemon's Ruby and Sapphire remake where you see the original game's intro on a portable device.
-there's an always available music player in the gallery on the lower screen, this is awesome! Plugged my headphones in and I'm stoked about these arrangements.
-the game looks the part on the 3ds screen but it's not perfect. For some reason sprites don't always appear pixel perfect despite the fixed camera. 3D elements on the overworld also display minor pixel crawl when you move around, which is a bit disappointing, since I assumed the fixed "2D" camera would make, well, a pixel perfect looking game.
-they've messed with how Mario and Luigi defend with their hammers. Previously defending for too long would see the Bros buckle under the weight of their hammers, this no longer happens, making an element of battles easier as there's always a reliable timing window for defending
-For what it's worth, they've also streamlined overworld navigation. You no longer need to micromanage the order by which Mario and Luigi walk in, which was essential to pulling off different moves in different ways. Now all the moves appear in a horizontal banner that you scroll through with L and R, and the game rearranges the Bros for you. I was a bit disappointed by this as I thought it, like the hammer buckling, played a part of the original game's character.
-You can fast forward all dialogue scenes by holding R which is cool. Though the game is pretty terse to begin with in its narrative.
-New Bros moves! Saw Super Bounce Bros, which works on two enemies. All Bros moves have Normal and Easy difficulties.
-The game feels just as tough as I remember, I actually just got a game over because I messed up defending twice and took too much damage. Luigi had fallen and it's still harder/slower to defend if Mario has to grab Luigi while defending.
So yeah, the game brought back some fond memories and it plays well, I just wish some of the more distinctive elements of it weren't streamlined. Especially as there's an easy mode in settings that could have been used for this. Still, if you love a good RPG you won't be disappointed with this. Especially so if you have fond memories of the original, the new presentation and soundtrack are really well done for the most part.
Hope this helps anyone itching for more information on the game! I didn't play Bowser's Minions but I plan to do so tomorrow.
