Haven't played the latest XCOM yet. Shame on me, I know. But I have fond memories of the originals.
There's a follow-up:
6 more ways to improve turn based RPG combat systems.
- Elevation effects
- Movement-focused special abilities
- Item drops
- Zones of Danger
- Death countdowns and revival
- Character-centric consequences
For Original Sin:
- Elevation effects
Don't know if we have that. Higher vantage point = combat bonus, attacking from below = malus. - Movement-focused special abilities
Fun stuff. Rescue ability for certain warrior types, spells like body switch, teleport, charge, moving or pushing enemies a step, maybe optional bonus movement at the start of combat. - Item drops
Encourage players to not stay in a corner but keep moving. Not sure if this one can be applied to Original Sin. - Zones of Danger
Dynamic environment. Sounds like we got that covered somewhat. Lava streams, puddles, occasionally active geysers, fire, smoke and other environmental oddities. - Death countdowns and revival
Unconciousness before death -- allows other characters to help their fallen comrades and revive them before it's too late. - Character-centric consequences
Direct gameplay effects during combat based on character traits like "greed", "jealousy", "compassion", etc. Read article for more about this.
