You liked Heroes of Might & Magic? Or perhaps King's Bounty or Age of Wonders? Stripped of all city management, you basically just have the turn-based combat. Braveland takes this and adds a big, friendly smile on every creature.
It presents you a cute, classic storyline: a happy farmer boy loses his family and farm to bandits and sets out on a bold journey for revenge, but it turns out there is something more sinister going on and the happy guy wants to deal with it. He travels around and beats up the bad guys who take the hits with permanent crooked smiles on their faces. At first the dialogue attemps some meme-based humour (arrow in the knee anyone?), but they are quickly discarded for cheerful, repetitive greetings and taunts.
Travelling happens on a board with enemies, stores and events in each tile. It's linear, though you can (and should) check every branching road for bonus items, gold and experience points. Gold gets you more troops and items, experience gives small bonuses to creature stats and increases the cap on troops.
While I only played the hard mode, combats are easy for a player familiar with turn-based strategy games. Combat AI does not offer surprises in neither good nor bad ways, so it's okay. There are only 7 different types of troops to buy and around the same number of different enemies with upgraded versions of the usual ones coming later into the game. Basically all of them also smile all the time.
Why, I even lost one battle! Being vastly out-numbered, my troops collected their pocket money and gave it to me to hire more troops for another try. Happyland would have been a more appropriate name for the game.
In conclusion, Braveland would probably be a nice introduction to turn-based strategy games for children or people not acquainted with the genre. For the rest of us it's just a small snack (it lasted ~4 hours for me) that gets a dusty taste towards the end. Get it on sale.
