I'm sort of mixed on it.
The thing I like about it is that it forces you to use characters you might not use otherwise and get you experimenting with the entire roster. I also like that it chooses a character for you and all that, because it would make the mode redundant if you just plowed through it with one of your 'mains' every time. It hasn't yet 'shown me the light' and got me using any new characters outside of this mode, but I've at least given them a try, which is a good thing.
I guess this isn't really anything I couldn't do by just selecting 'random character' though.
The bad being the exact same reason I never used Smash Run on 3DS...It's only local multiplayer, which means it's probably only going to be very occasionally that I'll ever use it since VS CPU is just waaaay too easy...
I also kind of expected a bit 'more', but I think that's mostly my own fault for instantly comparing it to 'Mario Party' when I first heard of it. There's theme matches like every item being a Mr.Saturn but it's largely just normal matches with random characters given to you.
I've not played it multiplayer yet (if I ever even get the chance to) though I expect it to be way more fun. Most games are most fun by default when you have a friend with you though.
I don't think I'll be using it on my own again though unless there's any more challenges than the ones I've done that pop up for it.
eh it kinda sucks, I mean it's ok it's just that IT GIVES YOU CUSTOM MOVES AT RANDOM. When I get a character I want it to be something I'm used to, not some completely random set.
I'm sure you can turn off 'custom characters'...Pretty sure I did it, because not knowing what moves I had was a step out of my comfort zone too far...Not to mention unfair against CPU's that obviously know what moves they've got whilst I'm trying to hide in the corner and find out...
