Yes, too bad graphics can make a game unenjoyable - even if the gameplay is really good.
On the other hand, good graphics don't make a good gameplay ( I wish developers of 'big' games like Battlefield etc. would think like that ) ...but if the gameplay is great, good graphics can make the overall appearance and 'feel' of the game even better
