There are good reasons to update classics. To make them available to modern consumers/new hardware. To fix critical flaws in the gameplay and interface. To fix things that were stupid in the original. To make the graphics palatable to modern audiences.
If a remake is not doing the above, don't bother.
If its a "spiritual sequel/reimagining" its probably just namewhoring and can be ignored too.
Though the PS2 Wizardry game ended up being the latter and its actually the best Wizardry out there overall. Accessible, true to the classic gameplay, graphics that aren't CGA, refined game systems as opposed to Wiz 1-4 that actively hated the player, (5-8 just didn't approve of you.) and available on a system almost everyone has and in a time where RPGs are played by more than a couple of nerdshoes.
But that sort of game is rare. Thankfully it does happen. Some of the Defender of the Crown remakes/updates did a good job of being either a reimagining or remake.
The Sierra VGA updates were pretty solid.
Ultima 1 was apparently a vast improvement over the Apple 2 basic version.
Bionic Commando Rearmed was excellent.
Sadly, the RPG genre doesn't get many remakes outside of the console arena. (How many times has Final Fantasy 1 been revamped now? How many times has Dragon Quest 1? Course those 2 franchises combined have close to 130 MILLION units sold and have the rabid fanbase to support remakes that keep the core gameplay intact.)
Id love to see the Ultimas all redone in nice graphics, with a solid interface, automaps, note taking, and a unified storyline that didn't get retconned into being stupid with each new release.
Bard's Tale deserves it. Something like Magic Candle should get one. While not really an RPG, I would resub to Xbox Live right now if I could play Warlords 2 Deluxe online. X Com with a little less abuse and map repetition, and some of the stuff later games had like close combat weapons.
Tons of these games were really before their time, or skewed too close to the Gygaxian BE SMART OR DIE TO BAD LUCK/EVIL GM concept.
I know this place isn't console RPG friendly, but Final Fantasy 7 really did bring the genre to the masses.
The problem is getting or playing a lot of these classics which at their core blow away the bad manga story with lots of random combat out of the water.
Trying to play some of them is too difficult for many, too annoying for others, and new folks are just gonna take one look at stuff like Might and Magic 1 and go running for the hills!
These days we can remove lots of boring level grinding, we can have nice interfaces. We can have the options for automaps, more guided storydriven adventuring, and less of whatever pee got into the Wizardry 4 developers' Corn Flakes the morning they wrote up the design document.
I mean, imagine a high res version of Adventure Construction Set. Given online communities the amount of tiles that would be made is astounding. (Yeah lots of them would be sprite rips of Final Fantasy. Ignore those sets.) It was still the easiest and most fun RPG maker out there. Yet nothing has come close since. They all seem to expect people to program and write scripts and such while being MORE difficult to use and more limited.
Imagine one that allowed for multiple players/party members. Options for Ultima 5 styled combat screens, or Bard's Tale/Dragon Quest styled first person views. Either 3d dungeons or top down/isometric. Conversation trees.
I'd like to say I am going somewhere with my thoughts but I am not and am just rambling now and dreaming of games that won't happen.
