Game version: 1.18
Decimal rating: 2.5
tl;dr: an otherwise competent product with chunky content hamstrung by lack of variety. Strong translation.
This review contains endgame spoilers.
Niramare Quest is a frustrating game to rate, in that it either shines or stinks (pun intended) with no in-betweens. Subsequently, two players can finish the game with wildly different impressions. The game is strongly attached to its core fetishes, and all fuckable candidates, from the party members to its legion of nameless NPCs, are either tall and busty, or chubby and bustier. The positions and moans, too, are recycled between characters. The game also prominently features piss, fart (complete with sfx), and futa (inc. one of your main companions voluntarily sucking off one) content, with a sprinkling of enema and scat. I would not recommend this title if these tags are a turn-off.
The game continues to struggle with variety outside of its lewd content. Weapons can have up to 3 modifiers (1 extra skill slot and 2 prefixes), but there's no reason to farm for the perfect combination because named weapons with objectively superior stats can be obtained either straight from the start or very soon after. Each location has its list of mobs and bosses, but most are a re-skin and very few have gimmicks (for example, the game claims its slimes are immune to physical damage, but they actually have higher MDEF than PDEF). Even the final boss is bland because her betrayal is disclosed to the player well before it happens.
Balance is another area the developers struggle with. The game is laughably easy. It hands out EXP like candy (literally, as about half of the mobs drop XP items that boost the entire party), and rains gear via infinitely respawning chests. Even a simple "collect basic medical herbs" side quest can bump you up a level from the XP payout. The only currency in short (but not finite) supply is the book tokens used to exchange for new skills, but that's "balanced" by those skills being crap. The most egregious case, however, is the lottery-exclusive gun. It not only boasts stats that would not be surpassed by anything until the penultimate boss, but it also guarantees crits. Even the final boss's second form can be two-shot by its standard attack, without any buffs, on the default (harder) difficulty. This weapon is obtainable before you even see your first fight, as you can repeatedly search houses for lottery tickets.
Ultimately, Niramare Quest is praiseworthy in some aspects, but, in my opinion, its drawbacks make it outstay its welcome. A porn game needs to stand on its game mechanics in addition to its lewd content, and this title cannot.
