To be fair, comparing a PS3 to a Wii is comparing apples and oranges. They are for very different audiences, for very different purposes. I own both and I enjoy both, for different reasons. While my setup at home doesn't let me fully get the PS3 'experience' (that's more what the PS3 is gearing towards - the overall experience), I do see what it's trying to do.
For the most part, I'd say it's doing it quite well, though the PS3's serious downfall so far has been the lack of games produced for it. The EB Games shelf in the store closest to me has only 2 shelves dedicated to PS3 games, off in a little corner. The Wii takes up a good 1/4 of the right-hand wall. Compared to the Wii though, is the *quantity* of variety of games much different?
Here's why I question it: many people who are "anti-PS3" see these two aspects of it as deterrants:
1) It's too expensive (which is true, it is expensive).
2) There aren't any good games for it.
Compared to the PS3...does the Wii have that many "good" games? Of course, that *entirely* depends on what you consider to be a "good" game. But what are the most popular Wii games (in no particular order)?
1) Wii Sports
2) Wii Play?
3) Smash Bros. Brawl
4) maybe mario Galaxy?
5) Zelda (which is also on Gamecube)
6) Mario Kart, when it's released internationally
Okay, there are a few well-known Wii games. Let's look at what are typically considered "good" PS3 games (aka. the most popular):
1) Dynasty Warriors 6
2) Gran Turismo 5: Prologue
3) Rock Band
4) Call of Duty 4
5) Devil May Cry 4
6) Assassin's Creed
There's 6 games for both systems for us to look at. Now, let's look at what else is available on both systems:
Wii: the majority of games are either
Mini-game/party games (and LOTS of them!)
sports games
(basically, games that promote casual fun among a group of players)
PS3: the majority of games are
Shooters
action/killing-things games
Racing games
(basically, games that can potentially look very pretty and be very immersive with a high-end home theatre system)
Bottom line:
The Wii is primarily geared towards good casual fun, typically in a group setting, though the potential is there for solo gamers. To be fair though, not many Wii games have much longevity as solo games.
The PS3 is primarily focused on creating a gaming *experience* for one or two players, perhaps more over an online/LAN game. The PS3 is for those people who prefer watching movies in the theatre because of the experience. If you don't get that *feeling* from watching movies in a theatre or an amazing home-theatre system over a "normal" TV at home, you probably won't see the "intended" appeal of the PS3, either. Again, to be fair, a number of PS3 games do suffer from lack of content (namely, many of the games are quite short).
As further proof of the fact that the PS3 is all about the immersive experience, here's a little "case study":
How many of you have ever played or seen Dynasty Warriors 6, Burnout Paradise, or other PS3 game with small text? How many of you have tried to read this text on a standard-definition TV? Yeah...it's almost impossible.
A PS3 almost Requires a high-def TV in order to be fully playable. Some elements of the game (text, map details, etc.) are literally impossible to see on a standard TV. Sad but true.
A more complex discussion is PS3 vs. X-box 360 but we can leave that for another topic.
(btw, I don't have a 360

)
Any thoughts?
