Well, easy is subjective. On top of that you have to account for online bravedo especially when dealing with a young crowd. A lot also depends on how intuitive a game is for some people also. See, playing Bioshock on "Normal" it *CAN* be fairly easy if you happen to pick the right powers, and decide to tackle those Big Daddies at the right time or with just the right combination of toys. But if you aren't that lucky, or don't figure out the strategies right away, it can be rough and you wind up doing the "respawn and chip away" thing.
When it comes to Dragon Age, people calling it easy, even veteran RPG players, are generally full of BS. Hundreds of save files is right. The company even acknowleged that the game was too hard even on the easiest settings and their patch reduced the difficulty somewhat to be more around where THEY said it should have been. When you see things like that happen it's easy to recognize bravedo.
Fighting games are a touchy subject, overall I'm not all that good at them. However I will point out that it's a genere unto themselves and people who are "into" fighting games typically play a lot of them. Even if the moves/engines are a bit differant certain skills like buffering moves and attack cancelling and the like are things that carry over between games somewhat. Someone new to fighting games is going to have no idea about this kind of thing. On a fighting game forum someone might list a "bread and butter" combo that requires attack buffering or whatever to do correctly and a third person reading it might just see a bunch of move inputs and wonder how anyone could possibly input the commands in that sequence givern the way the game moves. Also when you play a lot of fighting games you tend to think in terms of exchanges, and coming out ahead based on what options differant characters are going to have. Once you develop that way of thinking it changes EVERYTHING about fighting games.
Street Fighter IV is not an easy game if your casual, or only play sporadically even if seriously (like me). It too me quite a bit to get into a groove when I was playing and I thought Seth was a bit of a pain on Normal when I first fought him. However to someone who plays a lot of fighting games it's pretty basic. To be blunt it's a joke compared to say "Arcana Heart" on the PS-2, and Mildred would eat Seth for breakfast (which is a game I played a lot at one time, it took me longer to get into a groove with that one, and I still think Mildred sucks). The last Dead Or Alive game also struck me as having a higher learning curve especially given the general lack of ranged attacks (though I suppose some of the teleport moves like the one Ryu has come close), though admittedly as cheap as it was I don't think Alpha 152 was as bad as Seth.
But still I mean if like SF IV is your first fighter, or you play these things even more sporadically than me, I can see where it would be pretty gruelling since even in the training mode it seems to expect you do things that aren't exactly intuitive pretty soon in the process.
Honestly if I had to pick a good fighter for newbies right now I would actually suggest Blazblue's limited edition. That game is about as complicated as it gets, BUT it does have a DVD to teach you how to play that actually presents viable instruction and introduces complicated, but commonly used fighting game techniques, and frankly if you can get Blazblue down your going to be able to take away skills you can use with any fighter thereafter.
There was also a series about SF IV tactics that I believe started on XBL when the game first came out that was floating around on youtube that might be able to help a true newbie. It introduces concepts like exploiting hitboxes, and provides practical demonstrations of this. Say for example when most people throw a flying kick in a game they think "realistically" of impacting with the foot on an enemy's body. If your playing seriously you can't think that way but have to see things in terms of the "box" and the video demonstrates this by showing how a good thing to do is to jump OVER your opponent in a rather WTF fashion and hit the back of their box on the way down, in a way that makes absolutly no sense but does work. Getting hit like that is one of the things that actually causes some newbs to scream "hax" if they don't understand it (and it can be even more mind blowing and stupid seeming in other games).
One of the fastest ways to beat a real nub is to intimidate them by doing something to freak them out and damaging them in a way that makes no sense based on the animations themselves is one way to accomplish this. But due to poor design today it seems most people in that situation just ragequit the match so psychological warfare isn't half as effective.
