Pretty much this. Been playing Bowser for about a year or so in Brawl and I'm trying to use him in Smash 4 now.Bowser isn't a character. Bowser is a lifestyle.
I don't have Smash 4 yet so I've been playing it occasionally when I'm in London for tournaments or sessions with the London scene or up at my university's Video Game Society at the moment but I hope to save up enough money to get a Wii U soon.
It's like I go and play other characters for a bit, then I just instantly come back to playing Bowser. Maybe it's because I just like the 'disrespect' factor he can have in games at times. Just landing like 2-3 power hits = death or doing a Side B to your opponent whilst they're at kill percent and you look at their defeatist expression; knowing that they're going to get KOed.
It's quite satisfying making reads and it's pretty good that the character isn't exactly very complex to pick up. You don't have to learn tonnes of advanced techs or combos. You just have to learn how to hit the opponent, read their habits and punish their mistakes at least in my opinion.
That said, what I'm finding very difficult at the moment is finding a good secondary for Smash 4 Bowser at the moment. I only realised this after me and Ixis sat down and broke down Bowser's changes and weaknesses as a character in this game. Does anyone have any advice? I've currently been juggling between: Bowser Jr. , King D3, Wario, MK and maybe a bit of Marth.
