Is The Any Better Way To Do Sum For Multi Tables?

-- declare table
declare @Table1 table(ID int, Value int )
-- Insert sample data provided into table
insert into @Table1
select 1 , 2 union all
select 2 , 1 union all
select 7 , 2

-- declare table
declare @Table2 table(ID int, Value int )
-- Insert sample data provided into table
insert into @Table2
select 1 , 2 union all
select 5 , 1 union all
select 3 , 2

-- declare table
declare @Table3 table(ID int, Value int )
-- Insert sample data provided into table
insert into @Table3
select 1 , 2 union all
select 2 , 1 union all
select 3 , 2

-- declare table
declare @Table4 table(ID int, Value int )
-- Insert sample data provided into table
insert into @Table4
select 5 , 2 union all
select 2 , 1 union all
select 10 , 2


/*
Is there anyway I can write one sql query which will give me the following result:
IDs = All unique ID from all tables
SumOfAllValueFromAllTables =for the same ID, value from Table1+for the same ID, value from Table2 + so on ...

IDs - SumOfAllValueFromAllTables
===============================
1 - 6
2 - 3
3 - 4
5 - 3
7 - 2
10 - 2

--I have tried by the following way, but for more tables, it is becoming complicated, because I have 12 tables.

--Is there any better way to do it? Thanks for the help.

select coalesce(t1.ID,t2.ID) as IDs,
coalesce(sum(t1.value),0) +coalesce(sum(t2.value),0) as SumOfAllValueFromAllTables
from @Table1 t1
full join @Table2 t2 on t1.id=t2.id
group by t1.ID,t2.ID
order by IDs
