I've heard quite a few people claiming tower wars are dead.
This usually happens in the context of 'the server is dead, just look at how little happens with towers!'.
So, in that regard, I decided to produce some graphs. (you can mouse over them to get the exact numbers)
Attacks: (All Years) (Differential Graph) (Unique Orgs) (Unique Nicks) (Recent)
Results: (All Years) (Bar Graph)
Monthly graphs: Attacks, Results
Yearly graphs: Attacks, Results
Links for Atlantean and DNW graphs may be found here.
A comparison between the dimensions for the past year may be found here.
Unique (per month) attacking orgs: RK1, RK3
Unique (per month) attacking nicknames: RK1, RK3
Attacks per titlelevel: ('unique' only considers the attacker)
TL1: (Total), (Unique Orgs), (Unique Nicks)
TL2: (Total), (Unique Orgs), (Unique Nicks)
TL3: (Total), (Unique Orgs), (Unique Nicks)
TL4: (Total), (Unique Orgs), (Unique Nicks)
TL5: (Total), (Unique Orgs), (Unique Nicks)
TL6: (Total), (Unique Orgs), (Unique Nicks)
TL7: (Total), (Unique Orgs), (Unique Nicks)
Results per titlelevel: ('unique' only considers the attacker)
TL1: (Total), (Unique Orgs)
TL2: (Total), (Unique Orgs)
TL3: (Total), (Unique Orgs)
TL4: (Total), (Unique Orgs)
TL5: (Total), (Unique Orgs)
TL6: (Total), (Unique Orgs)
TL7: (Total), (Unique Orgs)
What I read from this is there's no noticeable difference between now and two/three years ago.
For some reason, last year was very active.
The only server which seems to be as dead as everyone claims AO to be, is DNW.
My hope is to be able to link people to this thread when they come with claims like described in the beginning in this post, and stop potential flamewars using statistics instead of adding fuel with partial observations.
All these stats will eventually be available through a easy-to-use interface at http://towers.flw.nu/
