I wanted to have some general rules of comparing the mods which I review, so here's my scale:
1 - Bismal waste of time with game-breaking bugs.
2 - An annoying time sink, potentially with game-breaking bugs.
3 - A broken or frustrating mess. Not fun.
4 - A bearable mod, but nothing more.
5 - An okay mod with prominent issues.
6 - An okay mod with prominent issues, but has redeeming qualities.
7 - A good mod with noticeable issues.
8 - A great mod with minor issues.
9 - A fantastic mod worth your time.
10 - A modding masterpiece and a must-play.
Also keep in mind that if I give some modder advice, their response and whether they try to apply it can influence my score.
Please bear in mind, that if I write a long review which lists many negative things, it's usually because I want to give you feedback on how to improve you mod, and not to put it down.
