Well I initially bought the 360 when the GTA4 came out, along with with a few games i had my eye on, like Mass effect, then just before Christmas i got my PS3 for MGS4.

Though both consoles do have similar games, there are few exclusives released and yet to be released that are worth owning the systems for. I haven't really looked into whats coming out for the 2 systems in 2009 as of yet, but i am really looking forward to Heavy Rain and Alan Wake. 

Because I own more exclusives for the PS3 and 360 each than I do for my entire collection of Wii games.

I actually have 17 PS3 exclusives and 17 360 exclusives. Kinda funny, but I only own 12 Wii games. There is more than enough PS360 stuff to keep me entertained.

Besides I couldn't go without having Valkyria Chronicles, Lost Odyssey, and Tales of Vesperia.

I bought my 360 for one simple reason, LIVE launch day. Most of my real life friends picked up a 360 so we game a lot together. With the addition of NXE and Netflix streaming, I would say Netflix if I were to buy one today.

I picked up a PS3 for Blu-Ray mainly and to play a couple of Exclusives people were hyping. Now that I own my PS3, I only rent games for it so far ( haven't bought one yet ) and play Blu-Ray movies. I ownly have 3 Movies in Blu-Ray but hopefully once they come down in price I will pick up more. That is if I don't sell/trade the PS3 and pick up a Wii. I have been tempted by my cousin to make a trade for the Wii and he give me $150.

I may just hold off and buy a Wii later or not at all. I do like playing with the Wii-mote on occasion but after a little while it just becomes annoying to me. Maybe if I owned one I would change my mind. By the way, there is nothing wrong with the PS3 or the Wii, I just use the 360 because that is where 99% of my friends and family play. I would probably have a different opinion of the PS3 if everyone was on the PSN.

i got both for the exclusives and because some friends only have a 360 or ps3.

Because both have different exclusives I want.  Could I live without God of War 3 or White Knight Chronicles?  Nope.  Could I live without Fable II or Lost Odyssey?  Nope.  So I bought them both.

PS3 cause Lair HeavenlySword Uncharted Resistance  MGS4 Resistance 2 LBP Home  KZ2 Will be huge!

Really cause of the exclusives like KZ2 cant wait!

360 Cause it was 200$

I picked up both the PS3 & a Xbox 360 because both have features/items/games that exclusive to each system that i wanted. Both platforms have exclusives that wanted (on 360 - halo and gears, on PS3 - Littlebigplanet, Socom). Also the 360 because that's the platform my friends have and wanted to play online with them. The PS3 is also a great multimedia device - for Blu-rau & watching pirated films

I just flat out love HD gaming.

I bought the PS3 because I love the Sony first party titles and I'm a big Final Fantasy / MGS fan. Even though that's multi, it's coming to Japan first (I know some Japanese) and Versus is as of now exclusive. Also, I was waiting for a format that was better than DVD before I started buying movies. Blu-ray did the job.

I bought a 360 for jRPGs only. Fable 2 and ToV are the only games I really like on the 360 right now. Lost Odyssey is a runner up with a few issues. Star Ocean 4 will probably be the next one. My friends love to come over and play Gears and Halo, so I do have them in my library. I rarely play those two games myself.

Well, the Wii. I don't see too much point in owning one before Dragon Quest X. I like Nintendo and Sony as companies much better than I like MS. All my friends have a Wii, so I can always play it when I want for Brawl.
