>>68ArabesA true veteran omo game dev, he's been making 3DCG games with good gameplay since 2006, when CG didn't even look that good.
http://www50.atwiki.jp/sgame/=ShikkinADV=
His very first game with simple visual-novel type gameplay and a few nice scenes.
Back in 2011 he remade this with nicer images since the CG girl in the first one was a bit scary-looking.
You play as Iwao, the recurring MC, and take a friend out on a date.
+Full translation patch exists
+Features desperation/wetting mostly with a couple of outdoor scenes
+- Simplistic gameplay, occasionally a bit clunky but it does its job
Rating: 7/10, pretty good for what it is.
=Shikkin128=
His most popular work before ShikkinSchool, in this game Iwao goes to a fireworks festival and takes photos of desperate/wetting girls to sell for money.
+A really nice variety of scenes and characters with a cool premise
+Fun interactive gameplay
+Partial translation patch exists somewhere.
+Features desperation, wetting, outdoors, and some toilet scenes
-As the oldest Arabes game without a graphical remake, some of the CG models look pretty dated. Depends on the girl.
-Can be a bit grindy since you start with a really bad camera and have to earn your way to a decent one.
I don't think you lose much by just using Cheat Engine to get enough money for the best camera at the start, since the core of the gameplay is figuring out how to unlock all the scenes.
Rating: 8/10, a classic.
=ShikkinPlus=
This one is more of a dating sim as you manage Iwao's daily life, raise stats, and meet the girls he knows in various situations.
+Lots of small nice scenes
+Ayumi best girl
+Full english patch
+Mostly only desperation and wetting
+- Gameplay is very simple compared to Shikkin128
-Also quite grindy
-Raising stats requires knowing trivia about omo scenes in a bunch of obscure japanese games/manga. The english patch supplements this a bit with an optional patch that changes all the questions to be about omo games/manga the english community would be more familiar with.
+Also features a 'Real Mode' which has three scenarios you need to figure out in realtime. I thought this was quite a cool gamemode.
Rating: 7/10, a bit ahead of ShikkinADV.
=ShikkinSchool=
Pictured in the gif.
Definitely Arabes' best work yet.
You play as a robot impersonating a teacher, controlled by Iwao, and you use your status to go around the school and cause desperation and other things among the students.
Featuring full animations for all the heroines.
Not officially finished as it still updates once in a blue moon, but there's a whole load of content.
+Animated omo scenes!
+Features: Desperation/Wetting/Toilet scenes/peeing outside/peeing in containers/pretty much a bit of everything.
+Wide range of heroines
+Enjoyable gameplay (It used to be pretty challenging but now there's an in-built walkthrough system now if you fail a quest too much)
-No translation patch yet, but the dialogue is quite simple and the animations also speak for themselves.
Rating: 9/10, this is one of the best I know alongside Mojiquest.
