The original version was fantastic and 5* on its own. The additional content added in Summer Memories Plus just makes the game absurd. Like, it's hard for me to comprehend and put into words just how good this game is. It's by far the best porn game i've ever played and i think it'll be very difficult for it to ever be topped.
You play a shota left to live with his busty older aunt and cousins for a month over the summer holidays. You set out to sex up the Aunt and Cousins, along with pretty much every other Milf in town. The story isn't groundbreaking but i've never really expected my porn games to have an incredible story so i don't hold it against it. It's simple and unobtrusive enough for me to give it a thumbs up. The main character is an inexperienced shota so at the start he's lead around the nose a bit by his family so if you're one of those weirdos that complains when a game has a main character that isn't an alpha chad called Xerxes straight from the very beginning then this is probs not the game for you. He gets more dominant as the game goes on, tho never really loses his "cute" appeal as the shota.
The atmosphere, the aesthetics, the audio, the visuals, the dialogue all make an incredibly comfy and cute atmosphere that fits like a glove with the Shota main character on his summer holidays setting, which makes it all the hot when the characters and plots all get more depraved as the game goes on.
The girls are numerous, all but one playing the busty oneechan/okaasan character to our naive and horny shota. There is one girl the character's own age but she's the hardest character to unlock and easily avoidable if that's not your deal.
The sex scenes are incredible. They start off rather vanilla but the content added into Plus just gets more and more depraved it's fantastic. Most of them are animated sprite sex which sounds boring but the sprites and animations are like everything else in this game... incredible. There are special events with handdrawn images. Not all images are mind blowing on their own but when combined with the audio, dialogue and general atmosphere of the game, it should always do its job of quenching your thirst.
Something to worth considering is that it might take a while for it to click on what you should be doing your first time going through the game. If you realized after 7 ingame days you've been wasting your time, don't feel bad about starting again the game goes incredibly quickly and there's a new game plus for any content you may have missed (with the new content in Plus, i don't think it's feasible for a first time player to get everything the first time round?) If you pay attention the game should be easy enough to figure out.
Only real negative to the game is the minigames. You need to do them for both the main girls and side girls and while some of them are easy and inoffensive enough, none of them are fun and some more annoying than others. The one for the girl on the beach and the one for the Athletics teacher in particular are a right buzzkill. But that's it. Thats the one flaw in this otherwise beyond perfect masterpiece.
