Having played through quite a few Sogna Hyper Animation Games (Viper Series), I’ve come up with what I Call my Hypertheory. Proof by game and character name. If a law has an exception the game and / or character will be listed below the law.
-Viper Games that I have played:
M-1 (English)
V16 (English)
GTS
CTR
M-5
RSR
Lanjerie Black (part of the Gokuraku Series and is not beholden to these laws)
1.The game will be short (2 hrs playing time)
Exception: Viper RSR (Took about 3.5 hrs)
2. The game will have a cute / pretty female main character and a sexy female main character, The sexy female character will be raped at least once during the game.
-Miki-CTR
-Carerra-GTS
-Kara -RSR
-Akira -V16 RISE (in all but two endings)
Exception: M-5
3.Extension to rule 2. The pretty / cute girl will be raped if you screw up in your choices in the game

4.Optional Law,There will be fights in the game that you will lose because the programmers and the storyline conspire against you.
