Crystal Defenders

Crystal Defenders (クリスタル・ディフェンダーズ Kurisutaru Difendāzu) is a tower defense game set in the Final Fantasy Tactics universe (as part of a collection of games known as the Ivalice Alliance).

The game was initially released as Crystal Guardians (クリスタル ガーディアンズ Kurisutaru Gādianzu) into three separate chapters for i-mode, Yahoo! Keitai, and EZWeb. The chapters were compiled and released on iOS under the new name Crystal Defenders along with a lite version available for free and later an iPad version.

Crystal Defenders would later go on to be ported to several different platforms since then, including Xbox Live Arcade, WiiWare, PlayStation 3, PlayStation Portable, and more.

Why It Sucks

 * 1) Very repetitive gameplay taking place in small fields. All you do is upgrade units, and place them, and watch them fight monsters to keep them from getting to the other side!
 * 2) *It doesn't help to see that it suffers from trial-and-error repetition on knowing which units to place. A majority of the time wasted on this game goes to it's so-called "trial and error" part before completing the stages.
 * 3) Repetitive soundtrack; soundtracks are used per 2 stages and some episodes re-use previous soundtracks, and said soundtrack is recycled from Final Fantasy Tactics A2.
 * 4) It feels like one of those Flash tower defense games that you can find online. The only unique element is the summons which are a double-edged sword; they do damage to your own crystals but do damage to the monsters, which aren't really worth it. Also, the game punishes you if you lose lives to the enemies, as it rewards you less gil when you clear a wave.
 * 5) All sorts of monsters; but they are barely unique from their Tactics counterparts with only resistances, flying, etc.
 * 6) The towers range from overpowered like crystal boosters to underpowered like the Tinkerer.
 * 7) Each episode is basically the same thing except with different maps and different units. Oh, and to top it off, the Fencer and Hunter are practically the same as the Soldier/Archer!
 * 8) Has nothing to do with the mainline Final Fantasy Tactics/Ivalice Alliance series outside of being set in the same universe. You could basically cut the Final Fantasy characters/monsters, replace them with generic towers/mobs, and nothing would change at all.
 * 9) And to top it all off, you get the full game on consoles like Xbox 360, PlayStation 3, and even the PSP, but for the WiiWare version, the game was divided into two chapters (titled R1 and R2 respectively) which have to be purchased separately.

Trivia

 * It should be noted that, so far, this game and its sequel, Crystal Defenders: Vanguard Storm, was the last Final Fantasy game to be set in Ivalice as of this writing (not counting remakes and/or re-releases of previous games). Square Enix currently don't have any known plans to make any more Ivalice games.
