Overall I liked 3 Stars of Destiny. It is an oldschool style rpg with a mix of interesting characters and some humor. The combat system is solid, it has good level design, lots of secrets, challenges, and achievements. With that being said, if you do not like snes style rpgs, there's probably not much I can do to convince you to like it. You either like this style of game, or you hate it. Nothing I'm typing here will change your mind if you hate RPG maker games. Please do note that unlike most reviews, I have actually completed the game. I would say it takes a good 25-30 hours on regular difficulty. On to the details...
The characters are unique without spoiling anything. There are some interesting ones and later in the game you get to split up the party into 3 groups so choices do matter. There's often funny banter between characters. Gameplay is pretty standard for an RPG. You will need to grind a bit to get some levels, but combat is pretty fun. Money will be in short supply until late in the game, so grinding isn't too bad or painful. There are also achievements and optional fights that are quite challenging. The dungeons, both indoor and outdoor are pretty massive. There are TONS of secrets and a lot of achievements and the game has replayability if you're inclined. You can try a speedrun, beat it on hard mode, find all hidden areas, etc. Also, if you do decide to get the game, without being a spoiler, be sure to check out the swamp area fully. There is a missable character and dungeon if just blast through it hastily!
The one negative point I would mention about 3 stars is the plot. I will admit the plot is weak and somewhat illogical at times. I would say that the later levels feel almost surrealist in nature as far as the theme of different level areas. If Salvador Dali created an RPG maker game, this might come close to it! Due to this, I would say that I really prefer Aldorlea's other massive RPG, the Book of Legends, over 3 stars. TBoL has a more cohesive plot and a ton of characters so I would recommend you try that one first.
So what makes 3 stars worth it if the plot isn't that spectacular? The gameplay and characters are both good and it's a very solid game overall. Interaction between the characters is pretty funny at times and that keeps things interesting. Great dungeons, fun combat, some tough optional bosses give it the core of a good RPG. Add in lots of replayability and steam achievements and trading cards and it's a good buy. If you like Aldorlea RPGs, it's solid and a lot of fun. If you're on the fence about this one, I'd say try The Book of Legends first for a more cohesive plot. You can also download a playable demo of both games from Aldorlea's site that will let you play the full game for an hour, just to get an idea of the characters and style. Hope this helps!
