I would say cost makes me more cautious or perhaps think about options more, but theme /layout/code of new games has a huge impact as well.
NIB games I've bought.
ACDC Prem - ACDC fan, liked the layout and toys and code
STLE - the warp ramp shot sold me, the code improved
MET - didn't love the theme, but great toys and art, and I waited for complete code
TWDLE - loved the theme and I thought the layout was cool
GBLE - loved the them, art, toys, layout
Passed on
GOT: didn't like the layout or upper play field
WWE - I didn't like anything about it
Kiss - didn't like the code, theme, or toys
Batman - didn't like the code, theme, toys
Aerosmith - like the theme, art, layout, Lonnie on code scares me...will wait and see
