Makes:
1. Great art, be it Daz or well drawn 2D. If using Daz, make use of the features and skip the default settings of the models (No more Daughter from Dating my Daughter or Older Sister from Man of the House)
2. Make body type/shape realistic. If doing a Milf, she doesn't need boobs the size of her head, or the MC doesn't need to be part horse.
3. If thinking long term game, build a small group of interactable characters and finish a few story arcs with them before adding more character to interact with. Most games seem to toss woman after woman at you to add to your harem, but waste chances to build the story with them as it is done.
4. Fetishes like bondage, submissives, flogging and whip play, electro shocks, machines. No scat, diapers or pee play.
5. Solid English and/or translations. Nothing irritates me more than playing a game that looks amazing but the developer is obviously not an English speaker and is using terrible translation software, if any, to tell a story.
6. Using the proper game engine for the game. Making a RPG? Use RPGMaker or Ren'py. Making a VN, use Ren'py or Unity, etc... Nothing more irksome than running around on a RPGMaker game, from point A to B to C for 5 seconds of interactions only to have to run all the way back to A after. Choose Wisely....
Breaks:
1. Kid looking characters. MC is a Senior in High School, his younger sister *ANNOYING ALARM SOUND* PERVERT ALERT!!! Pass. I've seen and read some very good games on F95Zone, but won't play them due to child looking characters in the game content. I'll leave it at that before I get into another Rule 7 rant..
2. Grinding is a chore, and nobody likes chores. I expect it in most games, but too much of it will cause a deletion on my computer
3. Minigames. While some games have minigames I enjoy and have an actual purpose in the game, lately it seems a lot of developers been tossing in minigames for shits and giggles, and its moronic. Need to boost your stats up, click the task to do it, fade to black, and viola, stat raised. Want me to mash the space bar as fast as I can for 5 seconds to do something? done, no problems. Don't make me do jigsaw puzzles, or mazes an shit.
4. Lighting. Figure this out early if doing 3D graphics. If don't know, ask questions of folks here who do. Don't be a Tremmi…
5. No win situations. Games are meant to be entertaining, they should not make me want to stab the developer with a spork. Don't give me a way to screw over a douchebag character just to have him turn the tables on me somehow and make me look like the asshole. Screw you Dark Silver!
6. Speaking of Dark Silver...Finish what you started. If your going to go all out an make a game, finish it. Have your whole game written out, character descriptions, backgrounds, plots and twists, etc. Have all of this done before you even think of beginning to make the game. Your time planning ahead should help you progress faster in makin the game and only thing that will slow you down is renders if going 3D.
