Well, Legacy says ...
pros SVBS:
1. easier than the ABS (maybe)
2. more appealing than a frontview (depends)
3. less work on the spriters ... (honestly?)
4. easier for people without reflexes (yes)
5. fancy effects (perhaps)
pros ABS:
1. just awesome (great advice :v:)
2. more realistic (i'll give this one to you)
3. keeps people awake (I don't know anyone who played FF falling asleep in mid-battle O_o)
4. more people would want to play (tune in below for this one)
5. more publicity!! (LMAO)
Okay ...
A SVBS is most definitely more appealing than the default front view in RPGXP, but any SVBS can be modified to give the battle a frontview feel with increased aesthetics. My personal opinion tells me that SVBS are more appealing than ABSs as well, simply because there is greater level of detail in all of the spriting, which brings me to the next point. EASIER on the spriters!?!? Are you mad!!??
Please explain how spriting a character twice the size of the standard RTP charaset is easier. Not to mention equipping them with weapons and merging the two together throughout all their animations, rather than just creating a spriteset of rotating icons. I don't really want to take all the time to get into this, but in a good SVBS, each character should have roughly 10-15 poses. ABSs for RPGXP don't have this many. Nowhere near this many!! Creating 2-3poses for a character in a SVBS is almost the same amount of work to create a fully animated ABS fighter. The sheer level of detail is the deciding factor in this argument. Depending on how many heroes and enemies are in your game ... I can't stand behind that statement, I'm sorry Legacy. I am shocked that's coming from a spriter!!
Like I said earlier, I have never felt SVBS are boring. If they were, they wouldn't sell ...
Let's the skill determine. Skill of what?? Pushing buttons on a keyboard!? If you ask me, I would rather select options and use my brain to maneuver strategic plans, than run around and mash buttons on a keyboard, not to mention how many keys are customizable in ABSs. Some may find this positive, but to me, it's just a hassle to try to keep track of all the shit.
More people want to play ... fail.
More publicity ... IDK. Final Fantasy has great publicity and always used SVBS style until very recently.
Generally, if your looking for a PC game, I would say SVBS all the way, but if it is on a console, then ABS.
