Isn't it the exact same game, though?
Sort of. I got it for free during a promotion (paid full price on 3DS, won a copy on Wii U and ended up with a Steam copy from a Humble Bundle, but 3DS is the best version now that it's updated with the Deluxe content) the controls on iOS are so much worse that the timer counts up instead of down, meaning you can take all the time you want in the iOS version.
I ask this every time and bumped the 1001 Spikes OT but got no reply... Did they patch the 3DS version yet? Last I heard was you couldn't play with unlocked characters. Still on the fence.
They haven't patched it that I'm aware, but not being able to play unlocked characters isn't entirely true. Just make sure you back up your save, because the game will freeze up when you take an unlocked character through the main gate (when the story sequence would normally show) but once you get back in, provided it didn't wipe the savegame, you'll be able to choose the next level for that character and move on.
Alright, I think I've talked myself out of buying Shovel Knight (for now). Now comes an even more challenging question: Fire Emblem or Advance Wars (initially)? I've only played the demo of Awakening on 3DS, but it seemed alright, and I remember playing and enjoying a good chunk of Advance Wars on the DS before getting a bit frustrated and setting the title aside indefinitely.
Alternatively, any essential VC/eShop games I may have overlooked (I don't have all that many) that you might recommend?
Bear in mind that FE: Awakening has the option to turn off perma-death, while the older titles don't, so if you're like most people you'll be resetting whenever someone dies. Advance Wars, on the other hand, gives you completely disposable units but lacks the RPG component.
