Hate to break it to you, but SSF4:AE was a freebie a few months ago. If you missed out, you might want to consider the Xbox version.
He missed the Amazon sale which was even better. I bought the SF 25th anniversary box for 69.99, which include: SSFIV AE with all DLC costumes, SFxT with all characters and most costume (doesn't include the alternate costume however), 3rd Strike online edition + SSFII turbo HD remix. At $150 it's insanely overpriced, but for $70 it's worth it.
I'm gonna give Tekken 6 a shot, since I completely skipped it for TTT2 (first Tekken game I didn't buy outside of the Tekken 5 revision). Continuum shift Extend for $12.24 is a good price, even if you can find it new for basically the same price on the PS3.
