GWN: "It's been a long time coming, but Capcom has decided to grand the wish every Street Fighter fan with the fourth installment (no counting spin-offs and updates) in the series. What can fans look forward to when it releases? Already released in arcades, we have some insight on what to expect.
Street Fighter IV not only features a healthy cast of characters, it also has in-depth fighting mechanics that should please hardcore fans. The largest introduction to SFIV is the focus attack which is essentially built up counter attack against your opponent. Think of it as building up adrenaline and then using it to counter your opponent with a surprise attack. Having played around with the focus attacks, it's safe to say that they add a new tactic for players to take advantage of within their fights rather than continually trying to string together large combos."
