Divinity: Original Sin (Classic)

It's solidly-built, has a beautifully-designed world, interesting characters, a great story, and a fantastic open-world feel.

If you'd like to engage in some good old school fantasy roleplaying that channels the pen & paper spirit of Baldur's Gate, mixes in some epic gameplay ala Diablo 3 and tops it all off with the high level tactical combat of XCOM and Jagged Alliance, do yourself a favor and buy this game.

I've always preferred using tactics during combat and enjoy having the freedom to plan out my moves, rather than engaging in a mindless clickfest or spamming hotkeys until they cooldown.

It has 70+ hours of content, enough exploration/quests to keep you busy the whole time, full campaign co-op, multiple companions you can bring (Madora and Jafar were my 2), a whole slew of attributes/skills/perks to build your unique character with, and just about anything else you would expect from an isometric RPG.

With the graphics cranked up to ultra the game is absolutely beautiful.

Character customization as far as your class, perks, talents, and skills is LIMITLESS.
