If you want a weekend or even a week of no sleep and constant gaming then get out the online PC games instead as this is mainly for the people who want to have fun and for the nostalgia.
We think it does bring back your childhood as we played these as kids and I tell ya, were still as happy with the graphics to date!
These are how we remember games and we are not 'with the times' where games take forever to load and are looking realistic, it spoils it for us, we like simplicity, fun and something you can even do for 5 mins or for a few hours and still not be disappointed.
With over 40, we still have some to get through but we love all of them, and I am sure our son will have so much fun with these when he's older.
I miss my megadrive and I still have my dreamcast and it all still keeps me very happy :)
My husband and I recommend this to anyone who played them as kids, wants a bargain or wants to remember what gaming is supposed to be about, entertainment, passing time, and even seeing who can get the high score.... there is too much stress nowadays, and games are now a top cause when back in the 80's etc, they were a relief/release from stress, something to sit back and forget about problems with :) I am so happy they brought this out!
