I'll break this down in two distinct aspects, for all 3 systems:
PS3-the PS3 is valued around 800-840 dollars, depending on which version you buy:http://www.playfuls.com/news_06601_PS3s_European_Launch_to_Reignite_the_Battle_of_Gaming_Consoles.html
Overall, it's one of the best deals out there, and certainly is worth the money.
360-Depending on where you get your information, the 360 is worth anywhere from 600-715 dollars:http://www.joystiq.com/2005/12/28/xbox-360-costs-715-to-make/
Another excellent deal in terms of what you're getting.
Wii-The Wii sells for just 250......but analysts and stat sheets show that the manufacturing price is just 158-200 dollars;http://www.engadget.com/2006/12/15/wii-manufacturing-costs-ring-up-to-just-158/
Overall, NO in terms of price. There's no sugar-coating it. This makes it the worst of the 3 deals.
DISCLAIMER: Okay, here's where my personal gaming expertise will come into play. . I've managed to play a good deal of each system. These following reviews reflect the experience that I've had with each.
PS3- The Ps3's heavy hitters right now are Motorstorm and Resistance. The Ps3 also boasts an enormous amount of quality multiplatform games as well. The PS3 also has a wide range of upcoming games as well, including lair, Ratchet and Clank Future:Tools of destruction, Warhawk, Killzone, MGS4, GoW3, FF13, and Heavenly Sword. Some sources say some of these may be out in September (http://www.gamespot.com/news/6168749.html
). I'm not sure about the exclusivity claims in the link though. I guess I'll wait there. Also recall that HOME and Littlebig planet are two excellent additions to the system. HOME, in particular, beats out any equivalent on another system.
The PS3 boasts incredible high-definition visuals, and has good online play. In my experience with PSN, I've never lagged or been booted from a match (a feat which is pretty remarkable). It's an excellent online service, and will probobly be the 2nd best we'll see this generation. Overall, it's definitely worth the money. Heck, I'm going to buy a 2nd one pretty soon!
360- The 360 Boasts the best library available in the present, as well as a strong line up in the future. At the present time you can pick up Gears of War and Lost Planet. The 360 also has strong multiplatforms that it shares with the PS3, which include R6V and Oblivion. Without a doubt, the strongest feature of the system is its online play, which is superior in every way to the competition. I'm not going to stretch this out any further than I have to- The 360 is currently the best system available. I'm going to buy a 2nd 360 (an elite version) as soon as possible.
Wii- The Wii entered the Console race without a quality lineup (much like the other systems). The only must-buy game at lauch was TP, which ended up being a bust (imho of course). Personally, I played very little Wii after Christmas time, because I got bored after playing it. My friends found the same thing when they played the system as well. The Wii does have some quality games coming out, including SSBB, Galaxy, Corruption, and Dragon Quest. Unfortunately, there aren't many multiplatform games on the system, which isn't cool. Despite not having the future lineup of the other two systems, the Wii has a noteable array of unique features
The most prominent "exclusive" feature is the Virtual Console. I'm not really a fan of this myself, as I own every Nintendo console along with their notable games. For the average gamer, however, this is HUGE. The 360 and PS3 don't have full backwards compatibility for their LAST GENERATION games alone. Without a doubt, this is the system's bread and butter in terms of features. Despite having a motion sensing remote, it sometimes acts as a hinderance (see Red Steel). This is why I tend not to glorify the feature. Overall, I do think the Wii will have the best gameplay in the future, which is a big plus. The Miis are cool as well, but they're overshadowed by Sony's HOME.
The only two other negatives are the graphics (which are archaic compared to PS360) and the online play (which is non-existant). I think that by the end of the console cycle the Wii will look as good as 1st generation 360 games, which is sufficiant. I believe that the Wii online play will be sufficient, and just a few steps behind PSN. Again, it really doesn't matter where each system's online play ranks....it's never going to be as good as XBL this generation. Overall, it's definitely worth the money as well.
EDIT: Already bought a 2nd Wii. My mother wanted one for mother's Day, so I went and got one for her.
So there you go. All three systems are worth the money. Note that this is my opinion. You can't take anyone's opinion (MINE INCLUDED) at face value. Play for yourself and see what you like.
