Currently, a number of islands are created for the sole purpose of artificially granting a lot of XP. I think an easy solution is to limit the XP awarded per island per day. I am thinking something like the following. The numbers can be tweaked.
- 10 x Very Small
- 8 x Small
- 4 x Medium
- 2 x Large
- 1 x Very Large
If this is accompanied with setting fixed values for the accolades, we will get more control over the awarded XP (less ways to exploit), and the added benefit of not needing a calibration period. Something like the following could work. Again the numbers are no final.
- Very Small → 100 XP
- Small → 200 XP
- Medium → 500 XP
- Large → 1000 XP
- Very Large → 2000 XP
To maximize the awarded XP, creators will simply vary the XP awards they add to their islands using more of the smaller ones. This all seems to align with the goals of the Accolades device.
