Never played Doom on comp but i played alot of ROTT til my friend showed me all the cheats kinda went really boring after that .
For long nights and lost sleep well Might & Magic worked great 6,7,8 .
Diablo 2 is what i´m playing mostly now
UT , Q3 and HL well they are great games but i just dont fancy them anymore, same same all the time give something new .
