Well I remember play this game in a friend's computer, but many things are quite blur now, sorry if I can provide you more information about it.

- It was a RPG.
- When you reach your carry limit, you could buy animals and use them as mobile vaults, so in this way you could create an animal caravan that follow you from town to town.
- By how it looks I could say was a '90s or perhaps early '00s (no more than 2005)

Sorry if right now I can't reward you with a game for your kind help, but probably in the not so far future I'll be able :D

I have absolutely no clue.

That was my guess as well....

Really sorry, what I mean was "mobile vaults", I don't know how I wrote that.

Probably Dungeon Siege indeed.

Thanks you guys! That was pretty fast ;)
Now I'm checking some videos to confirm if was Dungeon Siege or not.

Thank you all! It was Dungeon Siege indeed... oh man! the memories... On those days, my friend and I were really excited 'cos we play this game in his new PC: Pentium IV, 512 MB RAM, 256 MB video, was the first PIV we ensemble and the top he can afford to pay (we were only students and he buy it with his savings).
Will someday have it here, in our beloved GOG?

Apparantly published by Square Enix, a partner of GOG, and they sell the games stripped of multiplayer for less than $10 on Steam. So I wonder what's keeping them from offering the games here for $9.99 or so, apart from compatibility fixes (but if that was the only problem, GOG could have started working on them a long time ago).

I LOVED this feature in the game and don't know why more games haven't used it. It was so silly but real and also unique while being obvious (lil' bit rambling there no? ;) ). Oh and I would buy DS here for sure.

True, it's kinda surprising. Too bad that even in this game the pack mules became useless pretty soon since another party member is simply far more valuable than more inventory space (IIRC mules used up the same kind of slot as regular party members do).

Funnily enough I bought the original Dungeon Siege on Steam just recently and replayed it for the first time in years. I wasn't ever too fond of the game but in retrospect it's even worse. :/
