What marketing has been done from both sides shows very little of the gameplay. Marketing is all about how you can make people buy hype and want something. It's okay to be swayed by something like that, but it's not that smart to make final judgements based on marketing.
Sidhe have never really had a problem with graphics before, it's not something they've ever been bad at. They have done particularly well with this Rugby title in the graphics area, but the fact remains that Rugby League is the nearest they've produced to Rugby so far and the results were mixed to say the least (or perhaps to say the most). Still, I'm sure they have learned lessons and they could quite possibly produce something really special here.
My own view on the graphics is that they look quite sharp and impressive, yet the players have something of a baby-faced thing going for them, some of the proportions (giant hands) are a little wrong and some of the licensed likenesses are more questionable than the the really big names that they've modelled extremely well.
The colours seem extremely vibrant in an almost cartoonish fashion and although the contrasts are amazing within the conext of shadows and lit areas I find find that some of the colour aspects look a little to anime to me. It seems like the difference between the realism of Top Spin tennis (RWC, but less good graphics maybe) and Virtua Tennis (RC).
Don't get me wrong I like the graphics, but it seems a little off to me. To be totally fair though, this is their first rugby crack and graphically it's awesome for that.
