This list won't feature the VNs in order of "how good they are". Rating them would be way too much of a clusterfuck to me.
The VNs are not in their respective order. Meaning number 1 is not the best, and so on.
1_CHAOS; HEAD
2_Cross Channel
3_G-Senjou no Maou
4_Fate/Stay Night
5_Forest
This Visual Novel is the easiest visual novel translated to get a bad ending without using a walkthrough- which just adds to the fun
