PS4 Games
With the current Sony Playstation pushing current games makers to the limits we can only imagine what type of games will be possible on the new Playstation 4. Innovative games are being produced all the time with new concepts and online play, and that is only on the current console.
For example gamers found that they could not only play the levels on Playstation game Little Big Planet, they could actually create their own levels and allow other gamers to attempt them too. If as we expect Playstation 4 games carry on in this vein we can see the longevity in how long gamers play on one game increase. Instead of gamers becoming bored after completing a game, Playstation 4 gamers will be able to create new challenges and continue for as long as they want.
With previous Playstation consoles games have only a start and an end, meaning once they are completed gamers look for a new one. If the Playstation 4 console does a whole lot more as we expect, we can predict gamers will not amass as many redundant worthless games. I remember when I replaced my old PS1 with the updated console I had a Tesco bag full of games I only ever played for a week each. Again when I binned the old Playstation 2 I had quite a few old games but no where near as many.
If consoles keep improving and games keeping interest for longer, hopefully I will only throw out 4 Playstation games on my next upgrade!
