Tekken for me. Fantastic series, especially later installments - 3 and 5 in particular. Good to see a title with motion-captured moves performed by genuine experts in each martial art, and some non-mainstream styles thrown in the mix. The game has the benefit of being accessible to beginners due to the simple control layout - left kick, right kick, left punch, right punch etc - but the sheer depth and complexity of each character means there's room for mastery too. You can play one character for years and still keep finding new tricks and strategies.

Juggling is a handy trick when you can accomplish it, but usually it's just something that unskilled players whine about when they get beaten by a superior opponent. When two sufficiently skilled players fight, complex juggles are rare and risky. The weak damage caused by juggle blows sometimes fail to make up for the time it takes to execute them - the faster, more damaging blows are generally made with both characters on the ground.
