I have always had one console for each past generation. This is the first time I bought two consoles. I bought my wii and I love it, but there is a lack of hardcore games on it. And if I play a hardcore game I'm gonna want the best graphics, so I then bought a PS3.
With two consoles, I'm finding it quite hard, with a lack of money and time to play all the games I want on both consoles. So I've started thinking about selling my ps3 so I can buy more wii games, but resisting it because I might regret it later.
I'm hoping next generation, the next Nintendo will have a system with similar power to the other consoles and will therefore attract more hardcore games, so I won't have to buy two consoles.
Also, I will probably stop buying handhelds all together. I bought a psp, hated it, sold it. Then I bought a DS, loved it, but then stopped playing it because, again, money and time issues, and I would just rather buy console games.
