You have options, since you still need different consoles if you are really into videogames, but PS3 is the single most valuable in my opinion:

• It can’t be always decently emulated on PC
• Exclusives still today (mostly japanese)
• Games need space so they are best to buy retail, they are cheap and on bluray (great durability over time)
• You probably already have a 1080p display, so it work well on it.
• You can play movies and cd audio on it, so a great companion to every desktop PC
• Also eventually hackable if you prefer
