yeah acheivments are great
your points add on to your total points from your other games
and is shown over xbox live so other people can see it
and you can compare you games against others on xbox live
that has never happend with any gtas
look san andreas had new features like car modding and being able to gamble and even bmx and moutain bikes
and that was great i dont think gta 4 will let us down
maybe if the ammo will just get stored with the gun like in previous gtas
if the rl is in the trunk what would happen if your car blows up? will you loose you stuff
thats all true the countrside was great but gta 4 is set in the city(new york) and they dont have countryside in citys do thay.
if it realism they are looking for dont put any countryside in.
