Star Wars Galaxies.
An open world player can sandbox game in the star wars universe? thats teeming with potential...
and then it was released......
.....the buggiest MMO ever released by far, releasing without mounts, in huge open worlds releasing without player cities.
...one of the best crafting systems out there, indivudual resouces, everything player crafted was unique and degraded so it kept a good econmy going......yet even this system was limited by only having a handfull of things to craft EVERYONE doing top content had to look like
the HAM systems, so so retarded, you had people taking temporary stims to boost their ham up then strapping on the above armour thats they wouldnt ordinarily beable to wear, thus sealing themselves into their armour, you had riflemen and combat medics posisioning and damaging mind(which couldnt be healed easily)
then the free open skills system...revolutionary? no the buggiest worst system ever, FOTM templates were rife...unhittable TKM/Pikeman combos, combat medics throwing posions like bio terrorists, every patch it seemed something else became FOTM, the early pokemon wars of creature handlers throwing out rancors left right and centre, the smuggler tree never working, smuggling amounted too....opening sealed containers, the bounty hunter system which rarely worked.. then you have the original random jedi syystem of grinding through professsions giving the game the "hologrind" period of crapness and AFKing professions.
Damn i could go on, but boy did it have potential and you have to give SOE credit it was forward thinking i just think it was done 10 years too early before the tools and technology could allow them to do what they want.
