Every time another Steam sale rolls around I always grab a few extra copies of Terraria [official site]. I like to hand them out to anyone on my friends list who doesn’t own it yet. “It’s 2D Minecraft, but with actual character progression and loot and crazy monsters and and and” I tell them. If you haven’t played it yet, now is a great time to do so, since the long-awaited Patch 1.3 game will arrive tomorrow, June 30th.
The update adds a ludicrous amount of new stuff, as well as some much needed functionality tweaks. Like Steam multiplayer invitations to make playing with others much less of a headache.
