Playing through star channel 34 for the first time, kinda feels like the creator just gave up around "episode" 5 or 6 or so and just started putting out basic visual novel stuff from that point on. (I'm up to 9 now)Presumably he means
Part 1
Magic Shop
Part 2
Princess Trainer (Original)
Princess Trainer (with Mod by zomby games)
Part 3
Witch Trainer (Original)
Witch Trainer (with Silver Mod by silver Studio games)
Part 4
Star Channel 34
Yes, yes you can.
The events of the individual games are independent of each other. The only thing to mention about Witch Trainer is that Genie likes to experiment with potions and magic. Jasmine wants bigger breasts (basically Witch Trainer is an interlogue within the first Magic Shop game). While experimenting with his magic on Jasmine, something went wrong (again) and he ended up at Hogwarts.
So Genie ends up in Dumbledore's office and Albus Dumbledore ends up in front of a naked princess.
In Star Channel 34, there is an encounter with Severus Snape, who remembers his friendship with Genie from Witch Trainer. Hermione, on the other hand, remembers nothing.
Makes me respect Silvers and friends work even more.
