Actually, there aren't much differences between the two. The only major difference is the case it is in. The slim version doesn't even have a slot for the HDD, which is not even as good as the normal ps2 version.
The PS2 slim has less components than in the regular version, because over time Sony has found a way to combine components and reduce the cost to manufacturer. Both consoles are the same in that both of them can view up to 480p, and if anything, the normal version of the PS2 is a little better quality because it has less components to fail, otherwise, they are both the same. So pretty much..... Sony wanted to reduce the cost of making the ps2 by introducing the slim version.
There are also small differences between the two. The slim version has a flip lid instead of a disc tray in the normal ps2. The fan on the slim version is also a lot weaker.
Therefore causing the slim version to overheat a lot easier, which in turn may make the battery very, very, hot. It's not a good thing, but not a big problem either.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
