This is by far one of my favorite ero games, and I would encourage you to check it out.
Good:
*Artwork is beautiful. GA Corman is clearly an artist, I personally love the style which is sort of hand-drawn, Disney-princess/comic book-esque. Uses sound artistic principles (lighting, silhouette, color palettes, proportionality, etc).
*Sprites are GREAT. None of that default RPG garbage, chibi's are awesome. Probably some of the best sprites I have seen in any RPGMaker game.
*Cinematography. There is heavy influence from Sword & Sorcery films and cartoons of the 80s. He has great sense of visualization and cinematic technique (establishing shots, long shots, close-ups, perspective, etc).
*Story. The story appears to follows 3-act structure (hard to say as not yet complete), it is fun and engaging and well written.
*Dialogue is solid with different characters conveying different personalities and with different motivations.
*Humor. GA Corman is FUNNY. Like, actually laughing funny and I find myself actually wanting to read the dialogue which says a lot. Love your assitant Worm.
*Girls. Multiple hot chicks, doing requisite dirty things. Playing on different fantasy tropes that are very enjoyable.
*Strategy/progression. This is still a bit underdeveloped but the seeds are there. I like the progression in building up a base, gathering followers and gaining new equipment/armor/weapons. You have a warband advisor who manages the day-to-day of running a goblin war band. Its not super elaborate, but considering this is a one-man show being done as a hobby/side-gig (I think) this is incredibly impressive.
*Iteration. The dev has been responsive in his updates, fixing some of the grindiness of combat (random encounters) and adding in new content and improvements.
*Ambituous. I sincerely hope the Dev is able to finish this (I'm supporting him on patreon and you should too), because in addition to the story arc which is pretty large, the Dev has introduced animation (both dragon bones and hand drawn) and some slave-training mechanics that look VERY time consuming. The result will be impressive if he pulls it off.
*Kink. The ero stuff is very good but its a bit niche. Goblin on semi-reluctany girl action and some lactation fetish. Hey, that's cool to me but maybe its not your thing. Other than those two points, the sex scenes are fairly vanilla (in a good way) and well executed: BJ, doggie, tit-job, anal, etc.
*Music. Like the music selection, not sure if he ripped it, bought it, borrowed or composed it but not the standard RPG Maker crap and is appropriate.
Bad:
*Unfinished. This isn't strictly a bad thing, because hey, you have to start somewhere and this is pretty far along. But if you're looking for a complete game from start to finish, this ain't it.
*Ero-stuff not interactive. Think the Dev is actually working to change this, so it might develop into something really cool, but for now sex with the girls is mostly you click "sex" on a menu and then u get a couple of pictures with some dialogue. Half the games on this site don't have anything more than this, and GA Corman does it better than most, but it would be cooler if the sex acts meant something more to the game then simply getting a scene. Again, the Dev seems to be building out an animated, interactive, progressive sex system so if that pans out it will be amazing.
*Grind/balance. There's one quest in the beginning where you have to basically kill something like 6 or 7 different combat encounters that is really boring. I get it that is hard to come up with quests beyond fetch/kill quests but just grinding through half a dozen combats in a row is not exciting. Also there is one fetch quest where I had to look up where something was because it was not obvious at all. Maybe needs a hint system?
*Patreon-y. I get it, you have to do what the Patreon Gods decree, but some of the content should probably be a little bit less...consensual? I'm not talking about hardcore abusive rape but come on he's a friggin goblin and these chicks are supposed to be part of a slave harem.
Ugly:
Nothing about this game is ugly. Love the whole thing.
TLDR; This guy has talent. Seriously. If he completes this game it will be a true work of art. Maybe it's not your thing, but you can't say its not done well. Definitely follow this dude and support him on patreon and play this friggin game. Would give it 5 stars in a heart-beat if finished or a little more developed.
