Fishing For Winning Eleven PSP
Konami's WE/Pro Evo captain talks about possibilities for the handheld version.

For soccer fans, there are a number of choices out there, from the big leagues of FIFA to the dedicated team offerings of the Club Football series to the management sims such as Championship Manager. But for many, there are no choices after all -- soccer (or, shall we say, football) begins and ends with Konami's Winning Eleven. Also known as Pro Evolution Soccer, the series is a giant in Japan and Europe, and the upcoming PSP edition should take that success and run to the furthest reaches with it.
In an interview with Konami's European official site, the producer behind the series -- one Shingo Takatsuka, but also known under the nickname of 'Sea Bass' -- gave some hints about his plans for the PlayStation Portable edition of the series. The PSP edition is not currently in full production -- it's still in the concept stage, and the team is still evaluating the system to determine how best to approach the game, which was announced for the first time in May.
While the game isn't too deep in production yet, Mr. Takatsuka is excited for the WiFi LAN play of the system, and is eager to explore multiplayer with the PSP Winning Eleven. Interestingly, the concept of full 11-on-11 gameplay (where each gamer in a multiplayer session would be a set player on the pitch, particularly apt for a handheld since each player has his own screen) was mentioned as something in consideration, although not likely on PSP -- Mr. Takatsuka says it is technically possible (other than the fact that the PSP 's WiFi tops out at 16 players), but would likely not be able to replicate the exciting gameplay feeling that the series is known for, and isn't something he's ready to explore just yet unless it's something that the team has first worked out on home consoles.
Finally, the idea of exchanging data between the PSP and PS2 edition, particularly with the Master League team-management feature, is something that the team is very much interested in working on. The RPG-style gameplay of this extra mode seems most apt to Mr. Takatsuka because it does not require intense and exact control. (Between Metal Gear Acid, Armored Core:FF and now this comment about Winning Eleven PSP, we're wondering if game developers in Japan are taking some really rough, worker-bee's Z-train through some rough tracks into the office?)
Like the footie fans reading this, we're particularly psyched for the action part of Winning Eleven -- the widescreen format should be particularly good for capturing the back-and-forth play on the field (but yes, we're also eager to log some hours in that Master League management mode.) Look for more on Winning Eleven for PSP as soon as Sea Bass and company put some serious wind sprints into whipping the handheld game into shape.
