YMMV / Gal*Gun

• Accidental Aesop: Being overly lewd will make women not enjoy talking to you.
• Alternative Ending Interpretation: It's suggested that going with Aoi before the day runs out means he's lost his 'one chance' at love. However, actually, Aoi expresses her love for Houdai a lot differently, and if you look at the dialogue right, he DIDN'T miss out!
• Americans Hate Tingle: Double Peace had a mixed reception in the US. Some feel this way as they were expecting something different from Ekoro's guest appearances in other games (platforming/action)
• Crosses the Line Twice: The entire premise. The extreme, completely unapologetic focus on anything sexual a centimeter short of any actual sexual content on a rail shooter is so absurd that it wraps back around to hilarious and strangely charming.
• Good Bad Bugs: It's possible to make the Japanese characters shouted you to disappear by zooming in when they aren't on screen.
• Sequel Difficulty Drop: Gal*Gun 2 is noticeably easier when compared to Double Peace. In Double Peace, while most of the levels are manageable enough in difficulty, the boss battles required precise and quick timing with your controls if you wanted to get the best ending for the girl of your choice and it was rather difficult enough to accomplish effectively. 2 decided to drop the iffy prerequisites and made the boss battles easier, as well as adding more Anti-Frustration Features.
• Spiritual Adaptation: It's kinda like DNA²: The Rail Shooter (except with angels and demons instead of time travelers).
• That One Achievement:
  • From Double Peace: the Battle of the Bae: Ekoro achievement, as well as the Kurona and Patako ones (since they both fight exactly the same). You have to hit a small, fast target that fires multiple shots that force you to focus on them to avoid taking damage, yet still need to do well enough on your accuracy to get five stars. You can't wait until they stay still, either, since that costs enough time to ruin a five star time rank. And trying to do this from Score Attack Stage Select makes it even more difficult since you get stuck with no damage upgrades, putting even more time pressure on you.
  • Pretty Pictures from the same game can become this if you don't know how to unlock some of the CGs (or even know certain endings even have CGs). Get every major girl's true end? obvious enough. Get Ekoro's and Kurona's bad ends? not quite as obvious, but sure. Fail the Shinobu Window Rescue event? Not intuitive, but possible to accidentally get, given control issues that can pop up on the PC version. Get the bad end in Unseen Destiny? Not something you can accidentally do, and you wouldn't think to do it given that the character that's involved in resolving it already has a route.
  • Both played straight and averted with the Data Gatherer achievement, also from the same game and a sequel, which directs you to complete the profile for every girl in the game. The game has a profile for every girl, and there's three levels of completion medals you can get on a profile: Bronze, Silver, and Gold. Barring specific cases (e.g. Shinobu and Maya Kamizono), Getting Gold requires you to do three things: complete the entire left half of the profile (which itself requires getting their handbook, getting their three sizes, and using Doki Doki mode at least once), Obtain all three outfits in the profile view (which requires using Doki Doki mode on them in corresponding levels), and finishing Unseen Destiny with that girl. Silver only requires two of the three tasks done, and bronze is given for completing any one task. The Data Gatherer achievement thankfully only requires Silver medals (or better) on all profiles, so you don't have to do Unseen Destiny 70+ times.
• Woolseyism: Say what you will about Double Peace, but its English translation is pretty funny.
