Aokana Extra01 deals with just one character Mashiro' after story. I'm sure Aokana is awesome, and this will be an easy buy.
Eiyu * Senki Gold is an alternative universe take on the original game and kind of is an improved version of it. I will play this, though I haven't played the original. Seemed a bit repetitive and shallow, but could be fun. Will buy.
Mamono Musume is about a pirate who washes up on a small island. He finds a slime girl and a scylla girl whom ask to be trained up to be marine girls. I love monster girl games, so this looks like a must play. Will buy.
Princess X Fan Disc: Fiancees Forever is 13 episodes set after the original dealing with the original girls and others. I never played the first game, but I heard it was darker than expected and not too great. I need to play it first to decide if I get this. Maybe buy.
Song of Saya Remastered needs no explanation as it is a cult classic. I haven't played it so I will wait for the remaster, since it releases this month. Will buy.
Sumaga and the Baldr Sky games releasing this year is amazing! I've been wanting to play both for a while. Sumaga I believe had engine issues and Sekai was slow on the other two. Lots of good looking games that are must buys for me. Will buy.
Togainu no Chi is a BL game where Japan is divided after a third world war. It stars Akira who has a woman appear before him. He is forced to participate in a deadly game where you must take down the king to survive. Looks very unique for a VN story. I'm not into BL, but Nitro+ doesn't disappoint. Will buy.
Yamizome Revenger is a story about Kazunori who is normal guy. One day his soul becomes linked with a demon king. A goddess sends some heroines from another world to take him down, but they're weaker in his world. The demon king says he can control them and make them his harem. This looks a bit dark, but could have some fun overtones. Nonetheless it's a must play for me. Will buy.
9-Nine episode 3 is a must buy. Very pretty art and looks to be an interesting story. Will buy.
Alice Escaped!, Tobari 2 and Unity Union look like alright doujin games. I generally get those on sale. Nothing too amazing looking, but could be fun. Unity Unions is also a kind of beat em up/shoot em up like Dynasty Warriors, so it could be alright. Will buy with deep discounts.
Amatsutsumi is about a guy named Makoto who has the power to manipulate people with his voice. He leaves his village, but can't survive on the street. He ends up collapsing and meets a girl named Oribe Kokorom who can help him. Looks like it could be a really good one. It's from the same people who did Hapymaher (very good) and Chronoclock (decently good). One of my highest priority of the announcements. Must buy.
Love's Sweet Garnish 2 contains after stories for the 2 original girls and 2 routes for the others. The original was short but sweet and the other 2 girls deserved some routes. The first had a decent story as well. Will buy.
The Ditzy Demons was one of the funner nukiges I played this year. The fan disc contains after stories for the main heroines and full routes for the sub heroines from the first game. It also has a harem route. This will be a must play. I love the art in these games too. Play the first if you love fun nukiges. Must buy.
The Seventh Sign -Mr. Sister- is about a guy, and one day his sister shows up and has cat ears that come and go. This is a story about what they do about that condition. Looks short but sweet and could be interesting. Will buy.
Victory Project is a localized Chinese VN I believe that stars Ramon. He has been serving a life sentence for helping politicians to launder money. After 2 years in jail, he get amnesty and is sent to an island surrounded by beautiful girls. Supposedly the plot gets sinister or such after that meeting. This looks unique and has a story that doesn't sound similar to others. Will buy.
Glass, New Glass and SF are all short visual novels with real time 3D models. I might check them out, but i'm a bit unsure. Still will likely support them. I just don't like the 3D model games much, but these seem to have a story at least. Maybe will buy.
Magical Girl Alisa’s Quest looks like many other eroge RPGMaker likely games. I don't play these often if at all. I think I've only played one. Will buy on deep discount. The Secret Atelier looks like another of the 3D model games, but that may just be eroge scenes. Wont buy. Will buy both doujins cause those are usually OK.
Endless Torment is the story of an immortal slave girl who escapes the clutches of her horribly abusive captors and embarks upon a journey through the ages. I generally don't play these games, but the premise sounds interesting. Likely wont buy.
Sideboob Story 2 is set 5 years after the last game, and the kingdom is having dark times. Lute is bedridden and hasn't been seen for a month. A red haired amnesiac called Mask washed up on the harbor shore and is sent to fight a monster. Somehow I bet they're the same person haha. These games are really good, though the last one was a bit more repetitive in its storytelling compared to the first. These are some of my favorite medieval eroges. Must Buy.
Rance 1 and 2 I believe are remakes of the original games. I haven't played a Rance game, but they have a strong reputation. This seems like a good place to start. Will Buy.
