I quite liked the Knights of Pen and Paper games and this is VERY similar but with enough additions to make it worth a look I think.
Like the previous games this a meta experience but nothing pretentious, showing a roleplaying game from both the perspectives of the players AND the character they're playing. The type of person playing the character, their race and class all set up your first two heroes from their basic statistics to one-off abilities and proficiencies that play off each other. You'll get more characters as the game continues but even with just two characters you can make some fun combos like setting a de-buff with one character that the other can exploit.
In addition to the main quest (which tends to boil down to speedy turn based encounters like a classic JRPG) there's not a ship you can travel around in to new planets with new places to explore. Again this is ALL very slight in mechanics (very simple nodes to explore, combat, leveling is automatic, you don't equip weapons or armor you just slightly adjust stats with loot...etc) but it does make the fights feel separated by where they take place and what type of local creature you are fighting.
There's even ship combat, but this is basically just another turn based game of balancing shield recharging with attacks.
But for me the adorable sprites and amusing dialogue with nice subtle obscure references rather than in-your-face pop culture or fourth wall breaking constantly really makes this an enjoyable entry in a fine series. The players themselves and the GM seem into the game so it does feel like a labor of love rather than just a sneering parody of roleplaying.
For short sessions this is perfect. Set up a battle, a mission, follow the main quest, gather loot and money for supplies, test abilities. The grind is tough if you just use random encounters but the main quest, although challenging, provides plenty EXP.
Simple, cute, fun!
