Is Seasons worth the money?

For me, yes. It's added an element of atmosphere that in my opinion, the game needed. It's got me back into playing, and I'm enjoying gardening, heading to different towns to look for sunshine if it's raining in my town, and planning my events or outdoor activities around the weather.

ETA: I paid full price and don't regret it. If it had been on sale, all the better, but this is just about the only hobby I have and it's worth it to me.
