Could someone help me understand this game cover?

[dangkhoamnd_518210]

I recently bought a video game called Giftpia (ギフトピア) and before I start playing it, I'd like help understanding what the back cover says. I looked up all the Kanji and it's still not making much sense to me. Here we go:

大したものも
大したこともないけれど
ふと見ればそこは
贈り物に満ちたゆるい世界
大人になるための
日常の始まりです。

I think the first line says something about there being great ones, but my grammar isn't very advanced at all. Help is very much appreciated.
