My suggestion is to first play the this version normally and afterwards see if you missed something.
Naturally there will be a bit of spoilerage going on here, but I'll try and keep it vague.
This build is more of a "setup build" where I put smaller pieces into place for the next build.
That means there'll be less hardcore sex scenes than you saw during the first build.
Starfire - Anal! And she gets to watch you degrade her sister if you ask her.
Blackfire - You can give her four orders in total.
Jinx - You can give her one more order.
Beast girl has a total of four smaller girl scenes. When you reach 4/4 you'll reach an "under construction" - sign. Can be totally avoided if
you're boner doesn't get confused and is just like "NO. Nonono."
Kitten - You can meet her and her dad.
Terra - Nothing... okay, just a preview of her non naked body.
Bumblebee - A poster, you can also buy a Terra poster now from Yhads if you didn't get one from Beast boy earlier.
Raven - You get to fight/kiss/slap her bottom/see her nude etc. You'll reach an "under construction" - sign when you run out of her options at night.
The batarangs for Robin are cheaper and a bit more powerful.
There's a new enemy which is also pretty weak like Doctor Light and can help you get stronger more easily.
If you find bugs and/or have other feedback, you can tell me in the comments or if you want, simply send me a pm. it's all good!
Thanks and I hope you'll have some fun with this build!
