That's a personal choice. Your definition of in depth is subjective. Mileage may vary.
That's fine, your not/no longer a gamer. What you do is called killing time.
That is what gaming is

. Sorry, but uh, gaming is killing time. You really think you do something productive when you game? No, you do something fun that you enjoy in your spare time. And if it isn't your spare time.. then you're going to find it hard to pay your bills in the real world if you are so addicted to gaming you are doing it rather than the stuff you *need* to do (like go to work).
A sad possibility. Touch will never equal tactile feedback.
Depends on what you are talking about. RPGS like final fantasy? Sorry, really don't need tactile controls for that. In ways, touch is better cause you don't have to go scrolling for the command you want, you can instantly touch what you want to do.
Honestly, we can take your argument further. Your console games suck cause they don't have enough controls like a computer game does. For example try doing a realistic flight sim on a console? Ain't going to happen. You need a lot more ability to do a lot of commands (and quickly, not just scrolling through), something having a keyboard with a lot more ways to have different commands, gives you. I'm actually amazed some one did a decent flight sim (of course it has the same problem as consoles do, but actually if I were on a bigger screen like an iPad, it probably could be better than consoles cause they can just have you touch the controls on the "dashboard" giving you more options to control than a controller with limited buttons. So once again, touch screen is better than a control pad, but only if you have enough real estate on that touch screen).
Of course, for some games, the controller on a console is better cause you do want some simplicity. And then there are games like racing games where sorry, your controller SUX! I'll take my iphone's tilt control on a racing game over a frikkin d-pad or joy stick. Of course, the best for that is an actual steering wheel and pedals

.
What type of control is best depends on the game

. You can't just generalize here and you're being very short sighted if you think the controller is a end all be all and that there aren't things touch screen is better for.
I highlighted your problem in red. This is why IOS games are good enough for you. You've lost your gamers edge. This statement alone is proof of your non gaming affiliation. Since you imply that you are 'older" perhaps you attention span for the more in depth games is just not there anymore.
Compare Angry Birds to Mario? Cheesy?
I'm going to turn this around on you. Mario? Are you frikkin kidding me? Yeah, I am going to compare them both... they're both cheesy little games. What is with some of you people and your Mario love? There are far better games out there. And I hate how Nintendo just does Mario everything. Mario racing cart? Why not Gran Turismo? That's a far better and much more in depth racing game. Even Need for Speed is far better.
Mario is a great party game when you have people over I guess. Nintendo I suppose is good for kiddy games and social games. But honestly, I can't believe you're holding up the Mario name and having some sort of snub about being a real gamer. Mario is as much a time waster as Angry Birds (Which honestly isn't a bad thing, cheesy games that are just fun but you don't have to get into can be fun in their own right. But don't frikkin sit there and tell me I don't like in depth games and use *mario* as your example. Shoot, in general Nintendo isn't better for that really, they're "time wasters" are just in a different format. I would honestly think some one who cares about in depth would be more interested in Xbox or Playstation. I'm sure Nintendo has some but I am sure having a hard time finding any for the Wii my mom gave me).
I thought when you said depth you meant actually having a story and having to get into the game to finish it cause you need to get through all sorts of levels vs. this game is fun to play at any time. Most of Mario isn't something you need to get into for long periods of time, you can pick it up and play for a bit, play with others, have fun, but you aren't really getting into some extended play (I'll give you that Mario RPG had a story, but it still was more cheesy/humorous. I still prefer my Square soft RPGs, and even Breath of Fire IV).
Opinion, not fact. If it was possible to play iphone against hand held on a server with multiplayer you'd get your a#$ handed to you.
Well.
1. Usually multiplayers require the people run the same system so your scenario wouldn't happen.
2. I prefer solitary games to multi-player games (I will admit I'm not huge into games like Doom or whatever the equivalent is these days. The only shooting games I like are ones with a good story, usually horror story, like Silent Hill). My favorite games have a story that unveils as you play it, usually those are more solitary games. So I don't really care about playing against others.
3. Which makes sense I am not a huge Nintendo fan, it's great more for social and kiddy games. Sony and Microsoft cater more to my kind of games.
