This topic is basically a list of games that I've been really getting into that i highly recommend (as the title says).  To prevent the first post from dragging on so long (I.E. save space), I've put each game in their own spoiler tag.

Ninja Girls / Girls X Battle

Spoiler

PLATFORM = MOBILE **PLEASE NOTE: THIS GAME GOES UNDER DIFFERENT NAMES DEPENDING ON WHAT COUNTRY/LANGUAGE YOU LIVE/SPEAK** North America = Ninja Girls South East Asia = Girls X Battle Indonesia = Sexy Academy Thailand = Kawaii Academy Vietnam = Học Viện Tam Quốc **ALSO NOTE THAT DEPENDING ON WHICH VERSION YOU PLAY, YOU'LL RECIEVE DIFFERENT GIRLS.  FOR EXAMPLE, IN "NINJA GIRLS" YOU START WITH "REDEYES" WHILE IN "GIRLS X BATTLE" YOU START WITH "AQUARIS"** This game is an anime-style rpg in which all the characters you acquire and face are all anime girls.  The girls appear as collectible cards that you "summon" to face the opponent and their team.  There is a campaign mode (which the story is goofy, but bare-bones), a VS mode where you can face anyone online (Top Floor, Arena, & 1 On 1), and many more modes such as "Champion" (open a chest for prizes everytime you beat a team, difficulty increases with each gold chest opened), "Evaluation" (you can train and take challenges for prizes), "Infinity" (you face off against tough bosses with stipulations on how to beat them), and "Work Place" (you set up shop to collect coins/diamonds over time & can rob other players).  You can also set up your own guild and invite other people to join and take on challenges together.  Theres also a store where you can buy things with the coins/diamonds you win (along with other currancy like guild coins, champion medals, and 1 on 1 medals) Each girl has upgradable armor/equipment and powerful spells/skills (incuding passive skills) that are unlocked the higher the level/rank.  There are always events happening to mix things up, and the higher your acadamy level, the more stuff is unlocked to you.  Best of all, this is one of those games where you don't need to spend any real money on any of the micro-transactions (I've gotten though level 50 and up without spending a dime on this game). **PLEASE NOTE, THIS GAME REQUIRES SOME SORT OF CONNECTION (MOBILE DATA/WIFI) AS IT'S ONE OF THOSE "ALWAYS ONLINE" GAMES**

The Battle Cats

Spoiler

PLATFORM = MOBILE & 3DS

If you like Tower Defense games and cat related things then you should definitely give this game a try.  This is the first tower defense game I played and I enjoy it immensely.  You send a bunch of different cats to attack the enemies and their tower.  As you progress, you can acquire more cats, and upgrade them to different levels.  Each stage has treasures you can find that will increase a certain stat (like XP gain and cat unit attack power).  The battle system is simple, just touch a cat icon that you equipped on your team and let them do the rest. There's two different versions of this game.  The Mobile game, and the 3DS game (a.k.a. POP).  I recommend the 3DS version if you have a 3DS, because you don't have to worry about any micro-transactions since they are gone, plus you can play local vs with a buddy.  The downside is that their are only 3 chapters, unlike the mobile game which has double that plus more.
