Actually not true at all.
One of the biggest reasons so many amazing franchises have died over recent years is because developers try to make game play simpler, easier or more accessible in the hope of attracting more players, only to end up destroying the games identity and everything that made it popular to begin with thus completely alienating its fans in the process.
SE is no different. You can see it with Tomb Raider, Hitman. Dragon Age (wait is that SE?l) and Final Fantasy where pretty much everything that's been released over recent years basically flops.
If I recall it wasnt so long ago (maybe February) that Yoshi said the future of the Final Fantasy franchise needs to move away from mainstream audiences and go back to the fans...
XIII for example alienated a lot of Final Fantasy fans and is generally regarded as one of the worst games in the franchise why? Because it took away everything that made it Final Fantasy and all that was left was this giant corridor feeling from beginning to end because the developers wanted to make it easier and more accessible to players. They didnt want people to feel lost or overwhelmed trying to control multiple characters and various other things. Basically they ruined the whole game by making it super simple and easy.
XV sufferend many of the same complaints. The first part of the game was great but the second part once again became this long corridor and players were left feeling that so much stuff was cut from the game in order to make it easier and more accessible to players which is why there are so many holes in it's plot line..
This.
If you go and take a look at why so many big games franchises die, You'll see that focusing on making them to easy or simplistic in an attempt to draw in more players almost always ends up destroying everything that made the franchise great in the first place. It's a far to common occurrence..
The easier gameplay = more players doesn't work out better either. This is especially true on the mobile side of things. Sure 100 million people have played Angry Birds or something similar. But how many of them played it for any length of time... Yes its kind of fun for a couple of hours but gets boring incredibly quickly and the result is people drop the games just as quickly as they pick them up.. which isn't good for business in the long run.
