I o ly know sports games, so I cant really speak, but you just said it took Age of Empires have vision. Sounds like what I am talking about.
My question is, how old are you? Were you an adult in 2003, 2004 when we had 4 baseball video games to choose from? I am telling you, if EA had exclusive license in that time and to no, the games would be terrible. It took needing to be different to set yourself apart. Just being a copy cat wont work. Meter pitching came because EA wanted to make game play more enjoyable than just pressing a button to pitch. Playable minors, came about, because they wanted to bring in more buyers.They implemented analog hitting on NCAA. If EA had an exclusive license in that time, you would have deen none of this. It would have been new roster update each year, maybe a little tweaking. You have no reason to make your game better when you are the only choice on the market.
Again I'm not saying that EAs game will be good, hell it will take them a couple years to catch up like what is going on with NBA, but the long run of competition will only result in a better game, whether it is SDS or EA.
Madden vs 2K, NHL had multiple games for years, NBA had 2, hell there was EA vs 2K for college football and basketball. Most of all these franchises when they go to an exclusive license get last with innovations.
Lastly you want to talk about competition on sports games go back to 16 and 8 bit systems and look at all the games, each one tried to do something to set itself apart. Sports talk, vs having MLBPA license, season modes, full team customizations. Better graphics vs better interface. History has always show competition is good for the consumer, choices are a good thing. Business want to make money, you cant make money off me if i am not buying your product, because it is inferior.
