someone suggested this so I'm going to start it, I'm sure I'll forget a lot, as I'm not an expert by any means, so please feel free to add
1- there is no more wait to log in bonus, its gone, log in as often as you want
2- alliances are still around, just not the big server wide war
3- Bishop, lilgoodwitch, Mad Scottish, Palem, and many others are still here :)
4- new this age (55- Veil of Shadows), soldiers are +2 off/def instead of 1 for halflings, specs are 4
5- re-study the races and personalities- there is no way to have 100% of both thievery and mag ops anymore (unless you've figured out a way to combine the rogue and mystic personality)
6- IRC and UtoNet are still here, so is Utopia Temple but the Temple isn't used like it used to be
7- Pimp still exists but a lot of kingdoms now use Stinger
8- an a/t/m is possible, won't be the strongest in any category but its possible - its more like pick one role with a side dish of the other two
9- fog, ghost workers, and for the really long gone players boats, no longer exist
10- the lag at tick is no where what it used to be, same with the lag oop
11- there is recruiting and it's legal, kingdoms get so many invites free (they get more as the age progresses) and can purchase additional invites- go straight to the recruitment forum and see if anyone is offering what you're looking for, there's also the recruitment thingy on the lobby page
12- babysitting your province while you're gone is ok, need to purchase credits but it won't get you banned if you ask a friend to babysit, credits for babysitting really aren't much, i think it's $2.50 (American) for 5 credits which is more than enough
13- you can play on the same IP address with family/friends, just watch how your provinces interact- there's some guidelines which Bishop has posted
14- TFC (The Faery Circle)- is Palem's kicking group of faes
15 - CB's are now thievery ops - SOT, Crystal Eye is also now a thievery op
16- humans have become more of a t/m race
17 - there is a utopia wiki which gives a run down of well, pretty much everything, not 100% accurate but they try- click rules on the top of your province page and it'll take you there
18- there appear to be no battlefield or genesis rankings from the old days that I've been able to locate, I used to be able to see some but I think they're gone now
19- if you have a smart phone you can play on your phone through the internet browser (no angel for the phone though)
20- some kingdoms text each other regarding waves, mv, intel needed, etc- really its quite convenient
21- there is a report button, so watch what you say in the war forums, cursing can get you banned for a day or longer (depending on what you said) if its reported - and it kind of sucks not to be able to log into your province while your kingdom is at war
k- I just wanted to get to 21- someone else can take it from here
