I haven't played any of those, I should look into it. This is one of my favorite genres.
What's a good one to start with?
Of those I mentioned?
Wow, uh, tough to say. Basically, Wizardry Xth Generation either directly spawned or heavily inspired (as in, someone from the dev team joined another dev team which suddenly started doing DCs) like 4 games:
Class of Heroes
Elminage
Generation Xth -> Demon Gaze
Etrain Oddysey
In addition, there was recently a Japanese development push called the "Wizardry Renaissance" - a push to make new Wizardry games. We got one of those games, Wizardry: Labyrinth of Lost Souls, and it's expansion. I mention that because, IIRC, it was by one of the above's devteams.
W: LoLS is amazing. It's a true Wizardry game, using the original Wizardry's classes (With a Japanese bent -- for example, Dwarven women look like little anime girls, Gnomes are some sorta Brony Fursona thing, etc). It's hard as balls, especially in the end and postgame content. It got iffy reviews in the US media, unfortunately, because modern gamers expect an achievement every 5 button presses and the only game over screen you should ever see is the one you have to unlock ironically.
I believe W: LoLS also got an iOS port. Didn't touch it, as I use Android.
Elminage is amazing but you'll have to get past the somewhat odd localization. It's not the fault of the English publisher, their parts are perfect, as far as I can tell the Japanese dev team did the actual game mods, which have questionable English in them -- literally, they just put the Japanese into Google Translate. However, a 1.1 patch fixed most of that. It is one of, if not the original, "neo Wizardry" series game, adding the neo races that Wizardry 6 added and Japanese Wizardry games expanded on -- Catgirls, Dragongirls, Demongirls, Fairygirls... As well as the Neo Wizardry Classes added in the Japanese ones -- Alchemist, a Kung Fu fighter, a maid...
Class of Heroes 2 was recently released, and the expansion / rerelease for the PS3 will be out on PSN "soon." The sequel, Class of Heroes 3 for PSP/PS3 will be out "not as soon." 2 is a solid game although the English localizer thinks it's OK to redesign the game's systems - nerfing or disabling spells he thinks aren't balanced, for example. It's still a great game but that leaves a seriously bad taste in my mouth. It's still a must by - the game's great, the localization is amazing, and it's a lot of fun.
Demon Gaze for the Vita isn't out in English yet, and the other games by this particular developer haven't made it stateside. Generation Xth is getting an English fan patch but isn't done yet. I am on semi-Media Lockdown on Demon Gaze, although if it is anything like the previous games in the series the class system is based around you channeling, either via magic or scifi (DNA, yo), ancient heroes. For example, you're not a "Samurai," you're summoning the spirit of Oda Nobunaga, or somesuch. They all looked really good and I'm very excited for it. NISA is doing the localization and already has a Limited Edition up on their website.
Etrain Odyssey 4 recently was released, and a remake of EO1 was also recently released, both on the 3DS download store. I do not own EO4 or EO1R, I should fix that.
Edit: Oh, there's also the upcoming Conception 2, that might be worth a look at.
