That depends xP If it's something like a wall scroll or a figure, then yeah, but if it's like a model kit, the excitement stays till you build it. THEN it's gone XD
Anywho, PG is 1/60 scale. You are probably thinking of HG or RG, which are only in 1/144.
And what's hard about putting the parts together? The only issue I could see are the damn polycaps, and even then that's only if they're not seated correctly.
