So, here is my recommendations:
1. TheoAllen's Sideview Battle System
Me: Perfecto, this script makes my game awesome! (10/10)
Pros:
1. This Script. Is very cool! You would need this if you wanna make a game similar to final fantasy!
2. In the new version, you can make the enemy animated with the notetag <battler: (InsertFileName)>
Cons:
1. This script, requires lots of knowledge! You need to find Kaduki battlers.
2. A little bit hard to use for begginers! So be wary while using.
2.Yami's Battle Engine Symphony
Me: Tried it once, i like it! Maybe for my next game.
Pros:
1. Battlers move to the enemy/enemies while attacking, and swing their weapons.
2. You can set up skills like omnislash in your skills notetag! Awesome right?
3. Battlers walk in place when idle.
Cons:
1. You can find a 8D battler to make the script look more realistic, but so hard too find the pics!
2. If you die in battle, but don't have a 8D sprites to make you look dead. You will stand even if you die in battle. (I think Yami uses notetags to damage sprites)
3. However, if your battleback doesn't look optimized. Figthing huge enemies will make the player attack but they have to go high before slasing.
3.Enu's Tankentai
Me: However, i get errors with this script.
Pros:
1. Similar to Yami, the battlers walk in place when idle.
2. Costumisable skills, like Yami. Uses notetags for skills set up like Omnislash.
3. Baloons (icons, not baloons for kids), appear according to their stats (Critical, Poisoned, etc.)
Cons:
1. If you fight too many enemies, the script will give some stupid error.
2. Will be a disadvantage if you use this for games that focuses on huge enemy troop battles.
3. If you use a script that is translated, the translator even says that he cannot help you. So you must fix bugs alone.
That's all my pros and cons compilation, pick one!
