Life's too busy to learn tekken.
You are probably right, but Tekken is one of the most satisfying and interesting games I've ever played. Coming from a purely 2d background the look of the game took some getting used to, the way characters juggle and are hit, and bounce and move and so on.. initially the visual language of the game seemed off and weird, but it eventually clicked, and when I got to grips with the game play itself, and started to understand the general ebb and flow, I was blown away.
The game has it's own pallette of bullshit of course, and it can be hugely frustrating but games in Tekken has this wonderful texture to them, it's such an incredibly dense game that a good match is as good as a FG gets imo. In tekken frame data, like any fighter, is enormously important but you aren't a slave to it.. there is SO much more room to purely and completely out-think your opponent. Tekken has a lot going for it. It's the most balanced FG on the planet too.
That said though, it's not better than SF (or inj). It's just different. SF is scalpel sharp and precise with amazing feedback and feel of it's own and I am absolutely thrilled to come back when AE drops.
But Tekken is a HUGE legacy game.. shit from Tekken 1 still works lol, so to a degree, hours spend learning it will almost always have some value.. that's how I rationalize the tremendous time commitment involved.
