Vampire Hunter J:
not hot.
£11.95 + £8 x 5 (expansion packs) = £51.95
GOTY edition (including all 5 expansion packs) = £30 or less.
Just to clarify the DLC content is only available for XBOX 360 or PC, so for the PS3 I do not think you can, so the Game of the YEar is better value.
For the other ones, you could see it both ways, if you buy the expansions on their own you can trade them in after installing them and get some money back
When the expansions were released you could get them for about a tenner and trade them in for £9 at CEX of £10 at Gamestation (using price match + £1). So really it was cheaper that way as you only had to buy Mothership Zeta from XBOX live.
Otherwise the Game of the year is your best bet.
