I would like some advice for my project.

[DerVVulfman]

Just going down the list.

* Thirst/Hunger/Sleep
- Funny, but I was thinking the same thing just an hour ago. Something needed or else your health and mental stamina begins to depreciate.
* Appearance based on Changing Gear
- There are Paperdoll systems out there for RPGMaker XP. For the field (aka the map), I recommend Visual Equipment by Me™. And for the default battlesystem screen, I made Brenda's Visual Battlers that was modeled after Me™'s system.
* Random Loot drops
- Hrm... Just random loot drops... Can't think of any right now though it is familiar sounding. Perhaps something by SephirothSpawn or Trickster. All of Trickster's scripts are available in here.
* Cursed or Enchanted Equipment that must be identified
- As in 'before use' ? Well, I don't know of any that identifies BEFORE you equip it. Both Multiple Slot scripts by Guillaume and myself uses a system that lets you equip items and changes it to the REAL item (you equip a sword, it changes it to a cursed sword on equipping). Nice to trick people. The same principle should be easy to code. Basically a RIP from the system. I could rip it by tonight.
* Companions
- Guess you mean party members, or you have been playing with my MrMo's system to use the term (or you're a Dr Who fan). Are you intending a one-on-one only battlesystem? Battlesystem specific is it's own query.
* Day/Night system
- Well... I made my own. Check out Mellie Mel's Calendar system. ^_^
* a point and click style combat system.
- Oh, you saw mine. I did add [shift] to the system, to be sure. But that's because you want to differentiate clicking to move the player from clicking to perform a ranged attack. Seriously, would you want to step into your own bullet?
- Addendum.... MrMo's treasure drop allows for random dropped loot.
- Addendum.... MrMo's Paperdoll system: Lets you have visual equipment in the ABS (perhaps an ABS first for RMXP?)
* Skill Tree system
- MicKo's Skill Tree. ^_^ I'm using it too, in conjunction with other stuff.

I see you're using MrMo's (just got to that part). You were going ABS or something else?
