Radiant Historia was interesting to me because even your wrong choices led to end games that could be informative or neat. So even though you often only had one right choice and then a wrong one, the decision still FELT meaningful. Also the combat felt very... I don't know, it was more hands on.
Not only that but many of the bad ends in RH aren't so much the result of not just doing what the developers wanted you to do but because the other alternative was usually too inefficient to take and still prevent the doomsday scenario from playing out. Basically the game was really good at justifying why you just done fucked up (even if there weren't any dead man walking scenarios for you to play through). On that note, I will reiterate that RH's biggest failing was its lack of a budget. Looking at the game's official artwork, you can see that several locations looked a lot more impressive than they appeared in the game, moreover the aforementioned dead ends could've been expanded on or additional branches could've been added to give alternate perspectives on some of the events of the game and to make choices other than the first lead in different directions.
I'm okay with remakes when they're substantially different -- DQ5 on the DS changes a lot from the SNES version. CT was pretty much a straight port, though.
Technically speaking DQV is a port of the PS2 remake but it should count anyways since unless you've played the original through emulation or can read Japanese and imported the PS2 remake, it would've been your first experience with either version of the game. Whereas CT has had plenty of opportunities to be played and the differences between this specific version and previous are insubstantial at best. Even cases like FFIV can be justified by being rebuilt using a different engine and featuring different mechanical quirks like fewer enemies being encountered during battles and being made stronger as a result.
Are the Fire emblem games on the ds any good?
I thought Shadow Dragon was kind of average. Awakening for 3DS is awesome though. I also liked the GBA ones. Out of all of them Shadow Dragon for DS was my least favourite. It is a remake of the first though so it is lacking certain features available in later games.
Admittedly they weren't the best remakes. Much like the FF3 DS remake, the FE DS remakes tried to implement newer mechanics into games that weren't really balanced around them leading to such hilarity as Sedgar and Wolf becoming monstrous tanks after being reclassed into Generals and given a few levels to make use of their insane growths, Ceada and her four or so Win Spears making chumps of the game's massive number of mounted and armored forces thrown your way, the MU having such insane growths and 8 prologue chapters to use them in to make the other 75+ characters in New Mystery look like chumps, the wireless items/shops for ridiculous shit like Growth Drops, the Rainbow Potion, buyable Brave weaponry, and so on. Admittedly, I'd say as questionable as either FE DS game was, they're still better than the FF 3 remake by a country mile (the only changes that were pants-on-head retarded was increasing the stat caps on every class to reflect the GBA era games yet not do a thing for the bases making late joining characters useless by comparison, and making the difficult to access Falcon Knight class comparatively useless to the Dragon Knight class; whereas FF3 tried to make starting jobs more useful by nerfing the fuck out of the later jobs as well as providing an exclusive piece of gear if you stuck with a class for all 99 job levels, and to ensure that they'll nerf your stats for a bunch of battles after changing jobs even when you need to mass change jobs to handle the dungeon literally built around being in a certain job).
As for Shadow Dragon's Gaiden chapters requiring killing off the majority of your army to access, as lamentable as it is, I still have to give it props for helping break my habit of trying to save and use everybody evenly that I tend to fall into when I play FE games. It's encouraged me to try out specific runs based on certain arbitrary criteria like Marth + all females or Marth + all bald men. It's unfortunate that said requirements plus the lack of supports has everyone bent out of shape over the game (especially since Awakening's a good example of how tons of supports doesn't necessarily make the game that much better).
