An extremely average, low effort RPGM hentai game.
The art is nice, what little of it there is. The scenes are decently written, what few there are. But beyond that, everything is extremely basic.
The game is fairly short and mostly linear. The entirety of the game revolves around accepting quests at the Guild. Most of them are just you killing three of x enemy or collecting three of y item, then you report to the guild and get your reward. Even the main story requests aren't much different.
There are very few maps, all of which are small, and don't have much in the way of exploration. The battle system is the standard RPG Maker fare with nothing really added to it. If you want to get through it fast, there's a cheat chest in the tavern that'll give you a ring that amps up your stats, and then in battle you can just select the 'auto' option.
The hentai side of the game is your basic scene collector stuff. A few of the guild requests will lead to a sex scene (these requests are marked with a heart icon). Outside of those guild requests, there's a handful of scenes peppered around the town that unlock as you do main story quests. None of the sex events are forced on the player, as far as I could tell. You can easily do a virgin run, though I don't see why you would as there doesn't appear to be any reward or reason for doing so.
None of the events are repeatable and only three males have event chains, each with only three events and then an ending. The rest are random "click on heart icon on map, Teana has sex" sort of thing. Still, as I said earlier, the art is nice and the writing for the scenes is also good, though nothing exceptional.
There are a few gropers around the town but they don't lead to anything. Their content doesn't evolve with Teana's lewdness and nothing new ever happens with them.
Teana, the protagonist, has various sexual stats but they don't really amount to anything. I think you need a certain amount of lewdness to unlock a few events but Teana's lewd stat goes up so fast that it's basically meaningless. The only interesting thing here is that Teana's sexual stats also include her inner thoughts on the most recent event.
Not counting the endings, there's about 20 sex events overall. Combine that with only about 15 - 20 guild requests and you're looking at a pretty short game. You can probably zip through all the content in less than two hours.
The translation is fine. Teana's name often reverts back to Japanese or into symbols during sex scenes, and there were one or two quests with bits of Japanese in their description, but beyond that the translation was good. It's perfectly playable and understandable, you'll never get lost and the dialogue never degraded into incoherent MTL ramblings.
Overall, Glory of Teana is a painfully average hentai RPG Maker entry. Nothing really stands out about it but it also wasn't ever a chore to play. If you're really in need for a game and like the genre then it can be an okay-ish way to waste two hours.
