GET THIS GAME! Unless you're Maverick.
Zigfrak is a pretty awesome game. It's amazingly beautiful, but for reasons I can't begin to fathom it has never overheated my laptop. Not even when I accidentally left it running paused and the temperature in my room was in the mid-80s during the afternoon hours (my room sadly faces west). Even games that are 3D only as window dressing tend to overheat my laptop (RTS games, XCOM Enemy Unknown, and many others). This game I could probably leave running for a week.
This game is what I'd term a casual space RPG. What I mean by "casual" is that it tends to avoid the micromanagement most RPGs entail. Unlike most casual RPGs it IS pretty and there's a very wide variety of enemies and components you can add to your ship. No really, there's TONS of things you can upgrade your guns, shields, armor, missile launchers, whatever to. Going along with the casual game theme, they're often whimsically named. Inconvenient realism tends to get glossed over in this game. You're only allowed to carry so many of each object. Once you hit that amount, it automatically converts those items into the type of credits you spend at a trade station (there's at least three forms of currency, which makes game economics all kinds of interesting).
The author loves puns and references. There's an alien weapon type called "strange." So one of the weapons has an effect called "When you're strange." And given that certain of the higher-end weapon names are prepended with "tweaked" they put in one weapon called "Tweaked Morrison." The references vary between movies/sci-fi (obviously) but you can also find weapon types like Larry, Curly and Moe. I want to hope that Moe is the most effective, with Larry being the less-interesting mid-range model.
It's also a fairly sandboxy game. While there's an arcing storyline, you can freely ignore it if you want, and just go about fighting, looting, crafting or whatever.
The author is AMAZINGLY responsive and non-dickish (even when folks are being critical). Seems willing to take a look at your saved games in order to track down bugs (or just fix your stuck game for you). It's almost unbelievable how responsive he is given that it's a $5 game. I almost feel guilty mentioning that it's fairly easy to come by coupons for this game...
The only reason I mention my friend Maverick up top, it's not his type of game. While I wouldn't call the game overly easy, it rather shamelessly lists as one of its selling points that it's a click, kill and loot game. It even describes the things you kill as "loot pinatas." I like the honesty there, it lets you know that this wasn't done by accident or poor design. This game is for people who like getting loot. It's a nice palate-cleanser for my Shadowclan friends *snickers*. Money is easy enough to come by (and if you putter away a few hours in certain areas you'll be absurdly comfortable). You could also avoid doing as I did to get a "more balanced" experience. It shouldn't be TOO hard to get the things you'd want to buy (in the unlikely event they don't drop as loot somewhere).
