I'm not going to mince words with you here: serious (and some not-so-serious) non-Gundam war sims bore me to tears. I've tried games like Daisenryaku, Nobunaga No Yabou and Moe Moe Niji Taisen Ryaku. None of them have peaked my interest, and moe appeal couldn't save the latter because it depends on the generic stuff too much (and I'm not a big fan of mecha musume characters... I prefer my girls purely organic). If you enjoy some or all of the aforementioned, know that I have nothing against you and commend your far-reaching patience(or fanboy/girl-ism, whichever applies).
Idea Factory's Motto Nuga-Cel! seems like yet another moe-fied war SRPG ported from the PS2, but it put in a few hip recipes into the mix, resulting in a romp that is entertaining, and at the same time very challenging.
I've always been curious about otome games. Having played quite a handful of galge for the console systems I had before, I wanted to see what it was like to play a girl for once, and try to make a less-then-subtle appeal on the one bishounen I like the best. For Symphony ～with all one's heart～ Portable is one of Takuyo's earlier releases ported from the PS2, and the only title with both a galge and otome path.
Code Geass: Hangyaku No Lelouch Lost Colors is a galge based on the first season of the hit anime series, featuring full voice overs from the all-star seiyuu cast. Though the storyline remains intact, it's told from the viewpoint of another character who also possesses the power of the Geass. How he will alter the course of the war between Area 11 and the Holy Britannian Empire will be in your hands for once, though it remains to be seen if it can create enough of an impact to prevent the tragic fate of a certain main character. Anyway, let's just focus our attention on the here and now.
Sports games were never high on my list in the gaming department. I do sports from time to time, so the feeling you get by performing them for real is lost in video games. As a kid, I went through mini-golf once, but I never pursued the main sport in general since it seemed like too much of a bore. Trying Fantasy Golf: Pangya Portable was a major step outside my comfort zone, but I'm still playing it up to now and haven't regretted a single minute of it.
(Since I loathe the US versions, I'll be using the JP terms in my review. If you can't follow, then tough. : P)
Persona 3 Portable is the second remake (and first PSP incarnation) of one of the most celebrated PS2 RPGs of all time. Instead of an epilogue, the plot is revised a little to allow for the choice of playing as a female protagonist. The new girl has experiences unique to her path, and many of the Commu links were changed to match. Some elements from Persona 4 were also incorporated, making the gameplay experience markedly different from the first two P3s.
