Riviera: The Promised Land (Game Boy Advance, 2005)

Riviera: The Promised Land is a turn-based RPG game with some elements from strategy and dating sim games and a unprecedented gameplay.
The player takes the role of Ein, who must battle against demons as well as antagonistic Grim Angels to seal away the four Accursed. He is accompanied by four heroines — Fia, Lina, Serene and Cierra. By supporting these characters through decisions made in the game (for example in conversations) the player can achieve multile endings.
Nontypical the player controlls Ein indirect through triggers in two modes (Move and Look). In Move Mode, the player may advance to previous screens. Each area is made up of several screens, each screen having triggers to explore and potentially battles to engage in. In Look Mode, the player may press directional buttons corresponding to triggers shown on the screen. Unlike in Move Mode, many triggers will not appear until certain events have taken place and many triggers require Trigger Points earned in battle.
For every battle the player choose only three combatants, a position scheme and only four items, which can be used in battle. For every item each character has a different attack. Once all the preparations are made, battle begins. Turn order is decided by a count down. When a player character gets to go, they may select an item to attack. If the character is well trained with the item and the OverDrive Gauge is sufficiently filled, a power skill is available.
The game has one of the best art design and grafic i've ever seen in a GBA game.
At last: Riviera kept a place at the number 1 spot on 1UP.com's top 10 GBA games list throughout the majority of summer 2005. So I think this tells its own tale.
