Why do Sega keep making games exclusively for one format? Why don't they do multiformat games?

Makes no sense to me.

A really dumb decision..this was their chance to offer VF series to alot more gamers..some developers just never learn...it's just like the Square Enix thing

It makes perfect sense. Sony give you a bucket of money to make the game exclusive. If that money covers your projected earnings on other platforms, you stick to Sony's platforms. Otherwise you negotiate an exclusivity period and bring the game out on other platforms after that.

The thing is, Sony have a much larger audience at the moment, so Microsoft will have to offer huge amounts to get exclusives for the 360.

Nintendo will have an easier time of it with the Wii since the controllers will almost force games to be exclusive.

Another good thing about exclusives is that you, as a developer, can target the individual platform and make a game that is not a compromise. See God of War and PRG3, if they were multi-platform they would have been nowhere near as good.

Well thats all nice and they are all very valid points that I agree with. But the PS3 having a bigger audience than the 360...? ;)

My feeling is that the Sega brand is being weakend and diluted by all this one IP here, one there melarky. Only old school gamers really know what Sega is and is about any more. I just think they would be better served by making there biggest IP's multiformat. Like VT3 and Sonic are both 360 and PS3 bound.

Better question is, why does Sony keep making exclusives for formats on which their exclusives utterly BOMB on (every SEGA Xbox-exclusive for example) and doesn't release exclusives on the format that provided for them the best gamesales (being the GC)... and indeed moneyhats are the answer...

Screens suffer from the same problem as the DOA4 screens being "is this game meant for Xbox or Xbox360 because i can't see any difference with DOA3 really...." or better translated, because of their nature (only 2 characters onscreen) fighter-games as these have reached their functional graphical peak last generation, any other graphical improvement is entirely useless because well, who wants to focus on the enviroment in those kind of games?
