Alright I've gone through a good amount of the game and found some interesting things that may be useful to everyone.
-For a better fullscreen experience, press F1 then select fullscreen in the menu that pops up. Close the game and the game will be in proper fullscreen. I could be wrong but I think the image quality is a little better than just pressing F5
-To quickly gain H-EXP the game seems to expect you to have mid battle h-scenes. Just defend and depending on the animation, you'll get H-EXP for certain stats depending on the enemy. This is a little easier later when you have the seduce ability.
-The Knight route has more dialog (and for some missions, it's best you read it) but easier access to equipment to run through the game. The Resistance route has less dialog but more difficult to win battles (and don't get me started on how confusing the H-battle system is). I would actually suggest running through the Knight route first if you're actually aiming to play the game since it's a lot easier to level though the game this way and if you plan to run through a play through 2, it'll better equip you for that. If your just in it for the h-scenes but with context, you'll be grinding a fair bit more in my opinion but the Resistance route is for you then.
-If you want to still do some H-scenes in the Knight route, it's best you lose the first boss fight. Might be obvious but some scenes will only really play out when you're not a virgin. I can't say for sure though if you'll still be able to get the best ending in that route though (I think you can so long as that was the only loss and you just have 1 save for a perfect run and another one for fun times.
-I have some saves for the start of each chapter, if you need those, let me know.
