Halo - Adored the first two, not impressed by 3, Reach, or 4. However, I did enjoy ODST and Wars.
Battlefield - Trying to be too much like CoD now. Also, the franchise has become dominated by DLC and microtransactions.
Gran Turismo - GT5 was shockingly bad to me.
Street Fighter - Loved SF4, but DLC shenanigans and loads of re-re-re-releases or arcade editions and super editions and super arcade editions made me skip MvsC3 and SFxTekken.
Twisted Metal - My favorite franchise a couple generations ago. The 2012 game was rushed out broken and never properly fixed.
