That's why i said "it's complicated" lol about the 600 teams, i have no clue about it. But i figure it out that for example AFC CL will be an extra mode. Plus they've got 8 teams more than last year, and it's a lot of work.
I think to buy them all yes, as i'm editing a lot.
If i got some hope about the game, is because i saw AI, and they weren't that dumb as i thinked it would be. So it's a good point for offline. Now for the rest... Kimura said clearly it's a game "in building" and there will be more and more updates to come.
Even i think some gameplay changes, probably yearly. But i'm thinking the biggest issue as
@Sami 1999 mentionnned, is that you can't go rewind, if you preferred the older version. Except if they release a "Efootball 2"... We don't know, but i've readed carefully and that Kimura isn't that dumb as i thinked. It's not that i agree with him in all, but i understand his logic. Even gameplay talking. He really wanted a change, as PES got a bad reputation, they've did everything to restore the licence, even some pretty good version, but it was hard, and EA who were already rich gained more and more money. PS3 era was the start of the end of PES, replaced by FIFA (but i liked the guys behind Fifa's team, EA... It's another story, just the fact they killed some games like Top Spin and removed Bundes from PES was too much to handle for me lol, they were devilsh. Konami was a bit pushed by the events and became the same)
People buyed Fifa by default, like us when we buyed PES by default, even if FIFA 08 was overally better for example, i mean in terms of simulation. But i came back from the days, i like PES 2008 as a "PES 6 HD" with less effectiveness in pressing : i just tackle much more than on PES 6 to cut shoots and passes, that's the way Seabass wanted us to play. But technically, it was pretty rigid, and in HD the movements were too much flashy.
