For me a 'Metroidvania' type 2d game has always meant Castlevania a la Symphony of the Night. Metroid to me is always associated with Metroid Prime, one of my all time favorites. So another Prime would be amazing.
Even Prime on Virtual console would be pretty rad.
I guy at work came up to me yesterday (non-gamer, has kids) and proceeded to tell me a bunch of incorrect things about it that he was told or picked up incorrectly at gamestop (that it had a pack-in game, was launching with Splatoon 2, etc). So yes, it has entered the general consciousness to at least a small degree.
Well I dumped 70 orbs into the new hopper (picking red only) and I didn't get Eirika. Oh well, I did get 3 5 star characters including 5* Marth (the only other name I recognize). Boy are they over powered compared to my 2 and 3 star guys.
Yay, Sacred Stones characters are in, time to dump the 60+ orbs I've been hoarding. Now I have to decide, do five characters at a time for maximum efficiency, or only pick red slots for the character I want.
The exp thing is very welcome. There was a fine line between getting the smackdown and it been too easy and not getting any exp.
