Well, since we may well end up sealing Isaac's fate in SSB4 tomorrow morning, i wanted to nerd out about him just a bit. I feel like he really is the whole package in terms of a character choice. He has what any character for smash needs, and that is...
-Interesting attacks for a move set
-Stage options
-Music Selection
-History
I could go on and on about what a cool move set for him would be but I'd rather wait and see what he gets (unless he isn't in :/).
As for stages, I can really see a lighthouse being a stage (Probably Jupiter). It could have lightning bolt hazards and gusts of wind (see Temple in SB64) or flaoting/moving Zol, etc. But, what i would really like to see is the Belinsk Opera House as a stage, complete with chandelier dragon hazard. I would love to see that in HD and seeing as how pushed that whole ordeal was back in its time, I could see that being a favorable choice in locale.
The music selection for Golden Sun is pretty good IMO with the biggest criticism probably being that many of the tracks sound very similar. Having said that, I think there are many songs that stand out above the rest. Obviously "Battle with Saturos" would be in, I believe its in all three games. Other inclusions could be Jenna's Theme, Belinsk/Opera House, Forest's Requiem (I imagine it remixed to be more fighter-y), etc.
And above all, Isaac has history. Having more than 1 game is a big deal. He has a bunch of content that can make for interesting items, Assist trophies (C'mon Dullahan/Alex) and Stage hazards. And it doesn't end there, I truly believe we'll be getting a new GS in 1-2 years so this could be a great way to hype him up. (Imagine a Wii U release, how cool would that be!?)
I just wanted to get all that out before tomorrow. Crossing my fingers for his inclusion, even if we don't see him tomorrow. I know I'll be re-buying Golden Sun just to show my support for the franchise!
