Jon Hare mentioned in an interview that Sensible Soccer '98 was probably the worst Sensible Soccer game EVER, and PARTICULARLY the PSone conversion - which wasn't even done inhouse.
The PC version was at least playable, but I wouldn't rate it very high.
He also said in the same interview (from Eurogamer.net) that he was focusing on the things that made the originals so good while modernising it a bit. And I must say I really like the looks of the screenshots. Maybe we'll finally have an alternative to the more "realistic" games like FIFA or PES. This could actually be for football that Advance Wars is for strategy. Pure gameplay.
