This game was given for free by PSN plus members in January 2017. I downloaded and decided to give a try due to a have beaten all the physical games I purchased last years. I bought all LBP games but this is the first I tried to play to the end.
My impressions are:
1) Graphics: It looks slightly better than PS3 but no significantly better.
2) Gameplay: the same I remember from previous installments.
3) Story: the same tune when compared with the previous one.
4) Enjoyment: really good. It is not a long game so you don't get bored. The game is difficult just for a couple of parts. I felt challenge in some parts making you feel rewarded when you past that parts. Some level of achievements. The most difficult part was during the last mission. If die you have to start over again that mission, I mean, it doesn't have checkpoint. So you need to master each part by doing them again and again till you beat that last mission.
Considering that I was a free game, it is not a cheap one. It is a very well developed game that should be played just for a change.
If you downloaded for free back in January, just play it (give it a try, after few missions you will want to beat it all). If you didn't, just wait when It costs usd 9,99 to buy it and play it.
